وَإِذَا مَآ أُنزِلَتْ سُورَةٌۭ فَمِنْهُم مَّن يَقُولُ أَيُّكُمْ زَادَتْهُ هَٰذِهِۦٓ إِيمَٰنًۭا ۚ فَأَمَّا ٱلَّذِينَ ءَامَنُوا۟ فَزَادَتْهُمْ إِيمَٰنًۭا وَهُمْ يَسْتَبْشِرُونَ
And whenever a surah is revealed there are some of them who say: Which one of you hath thus increased in faith? As for those who believe, it hath increased them in faith and they rejoice (therefor).
Surah At-Tawba(9:124)
Sahih al-Bukhari
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: Sending 'Ali and Khalid رضي الله عنهما to Yemen
Narrated Buraida:
The Prophet (ﷺ) sent `Ali to Khalid to bring the Khumus (of the booty) and I hated `Ali, and `Ali had taken a bath (after a sexual act with a slave-girl from the Khumus). I said to Khalid, "Don't you see this (i.e. `Ali)?" When we reached the Prophet (ﷺ) I mentioned that to him. He said, "O Buraida! Do you hate `Ali?" I said, "Yes." He said, "Do you hate him, for he deserves more than that from the Khumlus."
