Those who permit sleeping during Jumu'ah

Hazrat Jariri says that Hazrat Abu Al-Ala used to fall asleep while sitting in the Friday gathering.

Hazrat Malik bin Dinar says that Hazrat Abu Alia and Hazrat Khallas bin Amr would sleep a long sleep on Friday and then stand up and perform prayer.

Hazrat Nafi' narrates that Hazrat Ibn Umar (may Allah be pleased with them) used to sit with his knees drawn up (habwah) during the Imam's sermon on Friday, and if the sermon became lengthy, he would place his head in my lap.
