“I heard a
man
asking Zaid bin Arqam: ‘Were you present with the Messenger of
Allah (ﷺ) when there were two ‘Eid on one day?’ He said: ‘Yes.’
He
said: ‘What did he do?’ He said: ‘He prayed the ‘Eid
prayer, then he
granted a concession not to pray the Friday, then he
said: “Whoever
wants to pray (Friday), let him do so.”’”
Sunan Ibn Majah Book 5, Hadith 508
