Abu Dawud quotes from Khalid, "Miqdam ibn Ma‘di Karb, ‘Amru ibn Aswad and a man of Bani Asad from the tribe of Qansarin went to see Mu‘awiyah ibn Abu Sufiyan. Mu‘awiyah said to Miqdam, ‘Do you know that al-Hasan ibn ‘Ali has passed away?' Miqdam quoted the Qur'anic verse that says we shall all return to Allah:
«إِنّا للهِ وَإِنّا إِلَيهِ راجِعُونَ »
"We are from Allah and to whom we shall return."
Mu‘awiyah said, ‘Do you think al-Hasan death is a tragedy?' Miqdam said, ‘Why should I not regard it as a tragedy when I know that the Holy Prophet used to put al-Hasan on his lap and say,
«هذا منّي وحسين من علي.»
"This one is from me and al-Husayn is from ‘Ali'."
‘Umru ibn Aswad said, ‘He was a fire that Allah extinguished.' Miqdam added, ‘But today will not pass until I bring you to anger because I must give you annoying news.' Then he added, ‘O Mu‘awiyah! If I tell the truth, confirm what I say. And if I lie, refute what I say.'
Mu‘awiyah answered, ‘Say whatever you want to say.'
Miqdam continued, ‘I swear upon Allah! Are you aware of the fact that Allah's Prophet (S) forbade men from wearing silk?' Mu‘awiyah ibn Abu Sufiyan answered, ‘Yes.' Miqdam said, ‘Do you not know that Allah's Prophet forbade wearing leather made from wild carnivorous animals?' Mu‘awiyah answered,
‘Yes, I know.' Miqdam said, ‘I swear upon Allah that I have seen your household engaging in all these forbidden actions.' Mu‘awiyah said, ‘I know that I cannot escape your accusations, O Miqdam'!"23
