Sahih Muslim , Book 5, Hadith 2226 (USC-MSA) ⓘ
Abu Huraira reported that the Messenger of Allah forbade (to do certain things) and then he made a mention of certain habits and said: 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.
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 " .
