Arabic hadith text
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الزُّبَيْرِ الْمَكِّيِّ، أَنَّهُ قَالَ رَأَيْتُ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ يَطُوفُ بَعْدَ صَلاَةِ الْعَصْرِ ثُمَّ يَدْخُلُ حُجْرَتَهُ فَلاَ أَدْرِي مَا يَصْنَعُ .
Translation
Yahya related to me from Malik that Abu'z Zubayr al-Makki said,"I saw Abdullah ibn Abbas doing tawaf after asr. Then he went into hisroom and I do not know what he did."
