It is written in al-Sawa’iq al-Muhriqah by Ibn Hajar that Imam Ali (A) said: “It is stated in the (Quranic chapter) Ha Mim that no one upholds our love save the faithful ones.” He then read: “Say: No reward do I ask of you for this except the love of those near of kin, and if anyone earns any good, We shall give him an increase of good in respect thereof; for Allah is Oft-Forgiving, most ready to appreciate (service).”(2) B.
It has also been reported in the same book that Imam Hassan (A) gave a speech in which he said: “Surely we are among the Ahlul-Bayt whose love and support were made incumbent (upon the faithful) by Allah, the Exalted. He, glory be to Him, said: “Say: No reward do I ask of you for this except the love of those near of kin, and if arty one earns any good, We shall give him an increase of good in respect thereof. For Allah is Oft-Forgiving, most ready to appreciate (service).” (3) C.
Imam Ali Ibn Al-Hussain (Zain Al-Abideen (A)) replied to the Syrian who said to him while he was a prisoner of the Umayyads in Damascus: “Praise be to Allah Who killed you..etc. ” Then he (A) said: “Haven’t you read the verse: ‘Say: No reward do I ask of you for this except the love of those near of kin, and if anyone earns any good, We shall give him an increase of good in respect thereof; For Allah is Oft-Forgiving, most ready to appreciate (service). ” (4) D.
Jabir Ibn Abdullah said: “A Beduin came to the Prophet (s.a.w.a) and said: ‘Muhammad, present Islam to me. ‘The Prophet replied: `Bear witness that there is no God but Allah, to whom an associate does not exist; and that Muhammad is the slave and Messenger of Allah.
‘ The Beduin said: `Do you require any reward from me (for bringing me to Islam)?’ He (s.a.w.a) answered:`No, save loving the nearest of kin.’ The Beduin then asked: `Mine or yours?’ The Prophet (s.a.w.a) said: `My kin.’ The Beduin said: `Let me pay allegiance to you, and may the curse of Allah be on those who do not love you and your kin.’ Thus he (s.a.w.a) said: ‘Amen.'” This narration has been reported by Al-Kinji in Kefayat At-Talib.
(5) Sheikh Allameh Amini (may Allah bless his soul) listed forty-five (45) sources in v.3 of Al-Ghadeer which state that the verse was revealed regarding Imam Ali, Holy Fatima, Imam Al-Hassan and Imam Al-Hussain (Peace be upon them all).
