Hadith
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يُحَرِّكُ رَاحِلَتَهُ فِي بَطْنِ مُحَسِّرٍ قَدْرَ رَمْيَةٍ بِحَجَرٍ .
Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to spur on his mount in the middle of Muhassir over the distance of a stone's throw
