According to ‘Iyad b. Himar al-Mujashi’i (ra), one day Allah’s Messenger (saw) stated in his sermon: “Behold, my Lord commanded me that I should teach you what you do not know and what He has taught me today. (He has instructed thus): The property which I have conferred upon them is lawful for them. I have created My servants as hanifs (having a natural inclination to the worship of Allah)” (Muslim, al-Janna, 63)
According to Ibn ‘Abbas (ra), when Allah’s Messenger (saw) was asked, “Which religion does Allah love most?” The Prophet (saw) replied, “The magnanimous Hanifiyya (that of the hanifs).” (al-Bukhari, al-Adab al-Mufrad, 108; HM2107, Ibn Hanbal, I, 236)
According to Abu Hurayra (ra), the Prophet (saw) said, “Religion is easy and whoever overburdens himself in his religion will not be able to continue in that way. So you should not be extremists, take the straight path and receive the good tidings that you will be rewarded; and gain strength by worshipping in the mornings, the afternoons, and during the last hours of the night.” (al-Bukhari, al-Iman, 29)
According to Tamim al-Dari (ra), the Prophet (saw) said, “Al-Din (religion) is sincerity.” Thereupon we said, “For whom?” He replied, “For Allah, His Book, His Messenger and for the (religious) leaders of the Muslims and for the Muslims in general.” (Muslim, al-Iman, 95; D4944, Abu Da’ud, al-Adab, 59)
Jabir b. Samura al-Suwaʾi (ra) said, “I heard the Prophet (saw) say during the Farewell Pilgrimage, ‘This religion will continue to be triumphant over those who are hostile to it. Those who oppose it and those who abandon it cannot harm it.’” (Ibn Hanbal, V, 100)
