‘Umara b. Ruwaiba said that he heard God's Messenger say, “No one will enter hell who has prayed before the rising of the sun and before its setting," meaning the dawn and the afternoon prayer.
‘Ubaidallah b. ‘Adi b. al-Khiyar told how he visited ‘Uthman when he was besieged and said, “You are a leader who has been accepted generally, yet what you see has happened to you, and a rebel leader conducts our prayer and we abstain.” He replied, “Prayer is the best thing people do; so when people do good, do good along with them, but when they do evil turn aside from their evil-doing.”
Qabisa b. Waqqas reported God’s Messenger as saying, “After my death you will have over you rulers who will delay the prayer, and it will be to your credit but to their discredit. So pray with them so long as they pray facing the qibla.”
