Sayf ibn Wahb reported that Abu 't-Tufayl asked him, "How old are you?" "Thirty-three years old," he replied. He said, "Shall I tell you a hadith which I heard from Hudhayfa ibn al-Yaman? A man from Muharib ibn Khasafa called 'Amr ibn Sulay', a Companion, was my age on that day and I was your age. Hudhayfa came to us in the mosque and sat at the edge of the people. 'Amr went over until he was standing in front of him and asked, 'How are you this morning (or evening), slave of Allah?' Hudhayfa said, 'I praise Allah.' 'Amr said, 'What are these hadiths which have come to us from you?' Hudhayfa said, 'What have you heard from me, 'Amr?' He said, 'Hadiths which I have not heard from anywhere else.' Hudhayfa said, 'By Allah, if I were to relate to you all that I have heard, you would be here with me until the middle of the night. 'Amr ibn Sulay', if you see Qays taking control of Syria, then beware and again beware. By Allah, Qays will not leave a believing slave of Allah without causing him to be in a state of fear or killing him. By Allah, a time will come to you in which the flood will not be stopped.' He said, 'Then what will help you against your people, may Allah have mercy on you?' He said, 'That is my business.' Then he sat down."
