[Machine] Bakr and Umar used to not take charity twice, but they would send it in the form of dates, grain, and fat in the drought, fertility, and lean years. This is because taking it from the Messenger of Allah ﷺ every year is a sunnah, as narrated in the past from Ibrahim. They increased in it, and they did not include its rightful owners nor did they delay taking it every year.  

بَكْرٍ وَعُمَرَ ؓ لَمْ يَكُونَا يَأْخُذَانِ الصَّدَقَةَ مُثَنَّاةً وَلَكِنْ يَبْعَثَانِ عَلَيْهَا فِي الْجَدْبِ وَالْخَصْبِ وَالسِّمَنِ وَالْعَجْبِ؛ لِأَنَّ أَخْذَهَا فِي كُلِّ عَامٍ مِنْ رَسُولِ اللهِ ﷺ سُنَّةٌ وَرَوَاهُ فِي الْقَدِيمِ عَنْ إِبْرَاهِيمَ وَزَادَ فِيهِ وَلَا يُضَمِّنُونَهَا أَهْلَهَا وَلَا يُؤَخِّرُونَ أَخْذَهَا عَنْ كُلِّ عَامٍ
