Also there is a narration from Imam Sadiq (a.s.) that this verse is for all the Quraysh who harboured enmity towards the Holy Prophet (S), fought with him and denied the Imamate of his legatee. It is related through reliable chains that people asked the Imam the explanation of this verse. The Imam asked: What do the Ahle Sunnat say about this verse? The narrator said: They say it was revealed for Bani Umayyah and Mughairah. Imam said: By Allah! This verse is revealed for all the Quraysh.
The Almighty Allah addressed His Prophet: I have given excellence to Quraysh upon all the Arabs and completed My ‘bounty’ on them and have chosen the religion of Islam for them and have sent a prophet towards them. So they have turned my ‘bounty’ into disbelief and destroyed their nation and made them reach Hell.
There is a tradition from Hasani in Sahifa Kamilah by Imam Sadiq (a.s.) that Allah has given all the news and happenings to the Prophet (S) which were to take place in the regime of Bani Umayyah on the Ahlul Bayt (a.s.) their friends and Shias. Then Allah revealed the following verse about them: Have you not seen those who have changed Allah’s favor for ungratefulness… (Surah Ibrahim 14:28) In this verse ‘favor’ refers to the Holy Prophet (S) and his Ahlul Bayt (a.s.).
There is a tradition from Imams Baqir and Sadiq (a.s.) and also Shaykh Tabarsi, Ayyashi and Qutub Rawandi have narrated in Daawaat that Abu Hanifah asked Imam Sadiq (a.s.) about this verse. The Imam asked him what according to your belief is the ‘boon’? He said: Eatables and cool water. If on the day of Judgement Allah makes you stand before Him and questions you about each and every thing you have eaten and drunk and all that you have drunk, then surely you would have to stand for a long time.
