Whenever we talk about our Prophet Muhammad (blessing and peace be upon him), the mind flows with every nice and aromatic speech, the heart fills with love and amiability and the human soul forgets its sorrows and concerns. Verily, Muhammad (blessing and peace be upon him), who is the worshiper in the cave of Hira, the one who came with the pure law, tolerant religion, the one who will have intercession and had the Night Journey, he will attain the praised position, will carry the banner, and will have the fountain, he is the seal of Messengers and Prophets. He is also the best of the pious, Imam of the righteous and the model for the successful people. The Lord of Al-‘Amin said about him: "And we have sent you (O Muhammad): not but as a mercy for the al-‘Amin" (mankind, jinn, and all that exists).” And He said: "And verily, you (O Muhammad) are on an exalted (standard of) character."O Messenger, Allah sent His blessings upon you, so days felt happy for your arrival.Souls were longing for you and pens were decorated because of writing your name.Prior to his mission, the nation was in a deep lethargy, so Allah sent him after a period of Messengers and Prophets and a big interval between him and the Prophets before him, and then Allah revealed the Qur’an, so the Messenger established justice.O Allah`s Messenger! We bear witness you have rendered back trust, informed the Message, and advised the nation, settled darkness, revealed the calamity, fought for the cause of Allah, and have guided Allah`s servants to the straightway. We also bear witness that you are on the straight path and correct creed. This Muhammad, who never strayed, never slipped, never humiliated, never cheated, and never felt tired (in the cause of da’wa). Indeed, he never strayed as Allah guides him and Jibril speaks and calls him. He never slipped as he is an infallible person and Allah aided him. He was never humiliated as victory accompanied him, he never felt bored and was bored as Allah was giving him patience and never felt bored because he had determination and a pure soul.This is Muhammad, the glorified, he is the imam and the example, wherewith Allah guides all who seek His good pleasure to ways of peace and safety, he taught the tongue invocation of Allah, the heart thanks ,the body patience, the soul purity, the leaders justice, and taught ruled people chastity. He made people like simple life; he was sent the Message, judged with justice, taught ignorant people, and guided people from going astray. He was elevated until got the highest position of Paradise, and was elevated until he got all virtues.This is Muhammad the sincere, Muslim reported through Ibn ‘Abbas (may Allah be pleased with him) "Abu Sufian told me that Hercules asked him: ‘What does he command you to do? I thought that he calls you for prayer, telling the truth, chastity, keeping covenant and rendering back trust.’ He said: ‘This is an attribute of a Prophet.’” Performing Allah`s rights such as keeping covenant, Al-Bukhari reported in his sound collection that Ibn ‘Abbas (may Allah be pleased with him): "A woman from the tribe of Johainah came to the Prophet (blessing and peace be upon him) and said: ‘My mother had vowed to perform Hajj but she died before fulfilling her vow, should I perform Hajj on her behalf?’ The Prophet (blessing and peace be upon him) said: ‘Yes, perform Hajj on her behalf. Would you not pay off any debts your mother might have left behind upon her death? Pay off what you owe to Allah, for He is the most deserving of settlement of His debts.’" The fulfillment of promise is a character from the truthful believers, Muslim reported through Abu Huraira that the Prophet (blessing and peace be upon him) said: “There are three signs of a hypocrite: when he speaks, he lies; when he makes a promise, he breaks it; and when entrusted, he betrays his trust." When the Prophet would make a promise, he would keep it. He praised Abi Al –‘As ibn ar-Rabi’, his son-in-law, saying: "When he talked to me, he would tell the truth and when he promised, he would fulfill his promise."  The Prophet (blessing and peace be upon him) showed that fulfilling promise leads to Paradise. Imam Ahmad reported through the tradition of ‘Ubadah ibn As-Samit (may Allah be pleased with him) that the Allah’s Messenger (blessing and peace be up on him) said: “Guarantee six things for me and I will guarantee you Paradise: Be truthful when you speak, fulfill when you promise, uphold your trusts when you are trusted, guard your private parts, lower your gazes, restrain your hands.” The Prophet (blessing and peace be upon him) praised Khadija (may Allah be pleased with her) and was loyal to her. Imam Ahmad reported in his musnad through Lady A’isha (may Allah be pleased with her) said: “One day, the Prophet (blessing and peace upon him) mentioned Khadija a lot, she said: ‘l felt jealousy of her.’ So he said: ‘You mention her many times. She was not but a such and such of an old lady and Allah replaced her with a better one for you.’ She replied: ‘Indeed Allah did not grant me better than her; she accepted me when people rejected me, she believed in me when people doubted me, she shared her wealth with me when people deprived me, and Allah granted me children only through her.’" An example for his sincerity is that when he slaughters an ewe and cuts the meat, he would distribute it to Khadija`s friends. When Hala, khadija’s sister entered, she welcomed her and offered her hospitality  and said: “Keeping covenants is part of faith.” An example for his sincerity to his homeland is that when the polytheists’ harm increased to him in Mecca, Allah commanded him to immigrate to Media then he went out of Mecca looking at it and said: “By Allah, you (Mecca) are the best of Allah’s land, and you are the most beloved of Allah’s land to me. If I was not forced to go out (of Mecca) I would not go out.” After eight years, the Prophet (blessing and peace be upon him) came back to Mecca to conquer it after he had to leave go out and when he came into it, he was very happy and forgave all the people despite of their harming to him. This is the best way to show sincerity to one’s homeland.Allah said: "And fulfill (every) covenant. Verily about the covenant will be questioned.” (Chapter of Al-Isra, verse: 34).To proceed, how great is Prophet Muhammad (blessing and peace be upon him) as a lover, beloved and sincere. He gave everyone his right and appreciated every one. He taught his companions (may Allah be pleased with them) love and sincerity. Verily, Allah says the truth as He says: "Say (O Muhammad to mankind): "If you (really) love Allah then follow me (i.e. accept Islamic Monotheism, follow the Qur'an and the Sunnah), Allah will love you and forgive you your sins. And Allah is Often-Forgiving, Most Merciful." (Chapter of Al--Imran, verse: 31).  Sahih Muslim, p. 736-737, no. 1773. Sahih Al-Bukhari, 353, no. 1825. Sahih Muslim, p. 56, no. 59.
