Sahih Muslim 1020
Sahih Muslim · Book 12: The Book of Zakat · The virute of giving gifts
Abu Huraira reported that the Messenger of Allah (ﷺ) forbade (to do certain things) and then he made a mention of certain habits and said:
حَدَّثَنِي مُحَمَّدُ بْنُ أَحْمَدَ بْنِ أَبِي خَلَفٍ ، حَدَّثَنَا زَكَرِيَّاءُ بْنُ عَدِيٍّ ، أَخْبَرَنَا عُبَيْدُ اللَّهِ، بْنُ عَمْرٍو عَنْ زَيْدٍ ، عَنْ عَدِيِّ بْنِ ثَابِتٍ ، عَنْ أَبِي حَازِمٍ ، عَنْ أَبِي هُرَيْرَةَ ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ نَهَى فَذَكَرَ خِصَالاً وَقَالَ " مَنْ مَنَحَ مَنِيحَةً غَدَتْ بِصَدَقَةٍ وَرَاحَتْ بِصَدَقَةٍ صَبُوحِهَا وَغَبُوقِهَا " .
He who gives a she-camel as a gift, for him is the reward (of the gift) both morning and evening - a reward for drinking milk in the morning and a reward for drinking milk in the evening.
