Khabab reported,

We complained to the Messenger of Allah ﷺ while he was reclining on a cloak in the shade of the Kaabah. We said, "Will you not seek Allah's help for us? Will you not pray for victory on our behalf?"He replied, "Among those before you, a man would be seized and a pit would be dug for him in the ground. A saw would then be placed on his head and he would be cut in two, yet that would not turn him away from his religion. He would be combed with iron combs that tore away the flesh and sinew from his bones, yet that would not turn him away from his religion. By Allah, Allah will surely bring this matter to completion, until a rider will travel from Madinah to Hadramawt fearing none but Allah Almighty, and the wolf for his sheep. But you are being impatient."

حدثنا يحيى بن سعيد عن إسماعيل حدثنا قيس

عن خباب قال

شكونا إلى رسول الله ﷺ وهو يومئذ متوسد بردة في ظل الكعبة فقلنا ألا تستنصر لنا الله تبارك وتعالى أو ألا تستنصر لنا فقال قد كان الرجل فيمن كان قبلكم يؤخذ فيحفر له في الأرض فيجاء بالمنشار على رأسه فيجعل بنصفين فما يصده ذلك عن دينه ويمشط بأمشاط الحديد ما دون عظمه من لحم وعصب فما يصده ذلك والله ليتمن الله عز وجل هذا الأمر حتى يسير الراكب من المدينة إلى حضرموت لا يخاف إلا الله تعالى والذئب على غنمه ولكنكم تستعجلون
