Hadith
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، سَمِعَ الإِقَامَةَ، وَهُوَ بِالْبَقِيعِ فَأَسْرَعَ الْمَشْىَ إِلَى الْمَسْجِدِ .
Yahya related to me from Malik that Abdullah ibn Umar heard the iqama while he was in Baqi, so he increased his pace of walking to the mosque
