Narrated Ibn Abi Mulaika:

Once the two righteous men, i.e., Abu Bakr and `Umar were on the verge of destruction (and that was because): When the delegate of Bani Tamim came to the Prophet, one of them (either Abu Bakr or `Umar) recommended Al-Aqra' bin H`Abis at-Tamimi Al-Hanzali, the brother of Bani Majashi (to be appointed as their chief), while the other recommended somebody else. Abu Bakr said to `Umar, "You intended only to oppose me." `Umar said, "I did not intend to oppose you!" Then their voices grew louder in front of the Prophet (ﷺ) whereupon there was revealed: 'O you who believe! Do not raise your voices above the voice of the Prophet..a great reward.' (49.2-3) Ibn Az-Zubair said, 'Thence forward when `Umar talked to the Prophet, he would talk like one who whispered a secret and would even fail to make the Prophet (ﷺ) hear him, in which case the Prophet (ﷺ) would ask him (to repeat his words).

Narrated Ibn Abi Mulaika:

The two righteous persons were about to be ruined. They were Abu Bakr and `Umar who raised their voices in the presence of the Prophet (ﷺ) when a mission from Bani Tamim came to him. One of the two recommended Al-Aqra' bin Habeas, the brother of Bani Mujashi (to be their governor) while the other recommended somebody else. (Nafi`, the sub-narrator said, I do not remember his name). Abu Bakr said to `Umar, "You wanted nothing but to oppose me!" `Umar said, "I did not intend to oppose you." Their voices grew loud in that argument, so Allah revealed: 'O you who believe! Raise not your voices above the voice of the Prophet.' (49.2) Ibn Az-Zubair said, "Since the revelation of this Verse, `Umar used to speak in such a low tone that the Prophet (ﷺ) had to ask him to repeat his statements." But Ibn Az-Zubair did not mention the same about his (maternal) grandfather (i.e. Abu Bakr).

It is narrated on the authority of Anas b. Malik that when this verse:" O ye who believe I raise not your voices above the voice of the Prophet, nor shout loud unto him in discourse, as ye shout loud unto one another, lest your deeds should become null and void, while you perceive not" (xlix. 2-5), was revealed. Thabit b. Qais confined himself in his house and said: I am one of the denizens of Fire, and he deliberately avoided coming to the Apostle (ﷺ). The Apostle (ﷺ) asked Sa'd b, Mu'adh about him and said, Abu Amr, how is Thabit? Has he fallen sick? Sa'd said: He is my neighbour, but I do not know of his illness. Sa'd came to him (Thabit), and conveyed to him the message of the Messenger of Allah (ﷺ). Upon this Thabit said: This verse was revealed, and you are well aware of the fact that, amongst all of you, mine is the voice louder than that of the Messenger of Allah, and so I am one amongst the denizens of Fire, Sa'd Informed the Prophet (ﷺ) about it. Upon this the Messenger of Allah (ﷺ) observed: (Nay, not so) but he (Thabit) is one of the dwellers of Paradise.

This hadith is also transmitted by Ahmad b. Sa'id, Habban, Sulaiman b. Mughira on the authority of Anas who said: When the verse was revealed:" Do not raise your voice louder than the voice of the Apostle," no mention was made of Sa'd b, Mu'adh in it.
