Sacrificing one extra sheep for every five
The Messenger of Allah ﷺ commanded us to offer a sheep for every five sheep as a charitable offering, and he commanded us to do ʿAqīqah with one sheep for a girl and two sheep for a boy.
أَنَّهَا قَالَتْ أَمَرَنَا رَسُولُ اللهِ ﷺ بِالْفَرَعِ مِنْ كُلِّ خَمْسِ شِيَاهٍ شَاةٌ وَأَمَرَنَا أَنْ نَعُقَّ عَنِ الْجَارِيَةِ شَاةً وَعَنِ الْغُلَامِ شَاتَيْنِ
