وَحَدَّثَنِي ، عَنْ وَحَدَّثَنِي ، عَنْ مَالِك ، عَنْ
نَافِعٍ ، أَنَّ
ابْنَ عُمَرَ " أَقَامَ بِمَكَّةَ عَشْرَ لَيَالٍ يَقْصُرُ الصَّلَاةَ إِلَّا أَنْ يُصَلِّيَهَا مَعَ الْإِمَامِ فَيُصَلِّيهَا بِصَلَاتِهِ "
It is narrated from Nafi‘ that Sayyiduna Ibn ‘Umar (may Allah be pleased with them both) stayed in Makkah for ten nights and continued to shorten the prayer, but when he prayed behind the Imam, he would perform the full prayer.
