وَذَرُوا۟ ظَٰهِرَ ٱلْإِثْمِ وَبَاطِنَهُۥٓ ۚ إِنَّ ٱلَّذِينَ يَكْسِبُونَ ٱلْإِثْمَ سَيُجْزَوْنَ بِمَا كَانُوا۟ يَقْتَرِفُونَ
Forsake the outwardness of sin and the inwardness thereof. Lo! those who garner sin will be awarded that which they have earned.

Sahih al-Bukhari
Food, Meals
Chapter: Al-Udm (additional food taken with bread).
Narrated Qasim bin Muhammad:
Three traditions have been established because of Barira: `Aisha intended to buy her and set her free, but Barira's masters said, "Her wala' will be for us." `Aisha mentioned that to Allah's Messenger (ﷺ) who said, "You could accept their condition if you wished, for the wala is for the one who manumits the slave." Barira was manumitted, then she was given the choice either to stay with her husband or leave him; One day Allah's Messenger (ﷺ) entered `Aisha's house while there was a cooking pot of food boiling on the fire. The Prophet (ﷺ) asked for lunch, and he was presented with bread and some extra food from the home-made Udm (e.g. soup). He asked, "Don't I see meat (being cooked)?" They said, "Yes, O Allah's Apostle! But it is the meat that has been given to Barira in charity and she has given it to us as a present." He said, "For Barira it is alms, but for us it is a present."
