Sahih al-Bukhari
Oneness, Uniqueness of Allah (Tawheed)
Chapter: ‘If I have been given what this man has been given, I would do the same as he is doing.’
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "Not to wish to be the like of except the like of two men: a man whom Allah has given the Qur'an and he recites it during the hours of the night and the hours of the day, in which case one may say, "If I were given the same as this man has been given, I would do the same as he is doing.' The other is a man whom Allah has given wealth and he spends it in the right way, in which case one may say, 'If I were given the same as he has been given, I would do the same as he is doing."
