وَحَآجَّهُۥ قَوْمُهُۥ ۚ قَالَ أَتُحَٰٓجُّوٓنِّى فِى ٱللَّهِ وَقَدْ هَدَىٰنِ ۚ وَلَآ أَخَافُ مَا تُشْرِكُونَ بِهِۦٓ إِلَّآ أَن يَشَآءَ رَبِّى شَيْـًۭٔا ۗ وَسِعَ رَبِّى كُلَّ شَىْءٍ عِلْمًا ۗ أَفَلَا تَتَذَكَّرُونَ
His people argued with him. He said: Dispute ye with me concerning Allah when He hath guided me? I fear not at all that which ye set up beside Him unless my Lord willeth aught. My Lord includeth all things in His knowledge. Will ye not then remember?

Sahih al-Bukhari
Holding Fast to the Qur'an and Sunnah
Chapter: Going deeply into and arguing about knowledge, and exaggerating in religion, and inventing heresies
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).
