Ibn ʿUmar, when pressed to travel quickly, would combine Maghrib and ʿIshāʾ” after the twilight had disappeared. He would say:
“When the Messenger of Allah (peace and blessings be upon him) was pressed to travel quickly, he would combine Maghrib and ʿIshāʾ.”
Muslim’s Sahīh records from Ibn ʿAbbās:
“The Prophet (peace and blessings be upon him) combined prayers during a journey he undertook for the expedition to Tabūk, combining Zuhr with ʿAsr and Maghrib with ʿIshāʾ.”
Saʿīd ibn Jubayr said: “I asked Ibn ʿAbbās, ‘What prompted him to do that?’ He replied, ‘He wanted to avoid imposing hardship on his community.’”
Likewise, Muslim’s Sahīh records from Abū al-Tufayl, from Muʿādh ibn Jabal:
“The Messenger of Allah (peace and blessings be upon him) combined Zuhr with ʿAsr and Maghrib with ʿIshāʾ during the expedition to Tabūk.”
Abū al-Tufayl said: “I asked, ‘What prompted him to do that?’ He replied, ‘He wanted to avoid imposing hardship on his community.’”
Indeed, it is established that he combined prayers in Medina, as recorded in the two Sahīh collections from Ibn ʿAbbās:
“The Messenger of Allah (peace and blessings be upon him) led us in Zuhr and ʿAsr together, without fear or travel.”
Another wording in the two Sahīh collections, narrated from Ibn ʿAbbās, states:
“The Prophet (peace and blessings be upon him) prayed seven and eight units of prayer in Medina, combining Zuhr with ʿAsr and Maghrib with ʿIshāʾ.”
Ayyūb said: “Perhaps it was on a rainy night.” The people of Medina would combine Maghrib and ʿIshāʾ on rainy nights, and ʿAbd Allāh ibn ʿUmar would join them. This has also been narrated as a report traced back to the Prophet (peace and blessings be upon him). This was a practice of the Companions.
