Abu Hurairah reported,

The Messenger of Allah ﷺ said to his uncle, "Say, 'There is no god but Allah,' and I will bear witness for you with it on the Day of Resurrection."He replied, "Were it not that Quraysh would taunt me, saying he only said it out of fear, I would have delighted you with it."So Allah revealed, "Indeed, you do not guide whom you love, but Allah guides whom He wills" [Qasas 28:56].

عن أبي هريرة قال

قال رسول الله ﷺ لعمه قل لا إله إلا الله أشهد لك بها يوم القيامة قال لولا أن تعيرني قريش يقولون إنما حمله على ذلك الجزع لأقررت بها عينك فأنزل الله {إنك لا تهدي من أحببت ولكن الله يهدي من يشاء}

Proof of the validity of Islam for one facing death as long as the death throes have not begun, which is the gargling sound, and the abrogation of the permissibility of seeking forgiveness for polytheists, and the proof that whoever dies upon shirk is among the companions of Hellfire and nothing can save him from that
