عَنِ ابْنِ عُمَرَ عَنِ
النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ كَانَ إِذَا اعْتَكَفَ طُرِحَ لَهُ فِرَاشُهُ أَوْ يُوضَعُ لَهُ سَرِيرُهُ وَرَاءَ أسطوانه التَّوْبَة
When the Prophet (sallallahu alayhi wa sallam) observed a period of private devotion in the mosque his bedding was placed for him, or a couch was put down for him, behind the column of repentance.* *A column in the Prophet’s mosque in Medina, said to have got this name because the repentance of Abu Lubaba was accepted beside it.
