"I saw Allâh's Messenger (ﷺ) delaying the Maghrib prayer till he offered it (along with the 'Isha' prayer). He used to pray Maghrib prayer three Rak'at and perform Taslîm whenever he was in a hurry during a journey. And after waiting for a short while, Iqama used to be pronounced for the 'Isha' prayer and he would offer two Rak'at and perform Taslîm. He offered any optional Salât never (prayer) till the middle of the night (when he used to pray the Tahajjud). [2:197-O.B.]
