It was narrated that Anas bin Malik said:
"The Messenger of Allah said: 'I have been tortured for the sake of Allah as no one else has, and I have suffered fear for the sake of Allah as no one else has. I have spent three days when Bilal and I had no food that any living being could eat but that which could be concealed in the armpit of Bilal.'"
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنْ حَمَّادِ بْنِ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ لَقَدْ أُوذِيتُ فِي اللَّهِ وَمَا يُؤْذَى أَحَدٌ وَلَقَدْ أُخِفْتُ فِي اللَّهِ وَمَا يُخَافُ أَحَدٌ وَلَقَدْ أَتَتْ عَلَىَّ ثَالِثَةٌ وَمَا لِيَ وَلِبِلاَلٍ طَعَامٌ يَأْكُلُهُ ذُو كَبِدٍ إِلاَّ مَا وَارَى إِبِطُ بِلاَلٍ ‏"‏ ‏.‏
