Combining two prayers while traveling is one of the dispensations which Allah has permitted for His believing servants - to grant ease for them and remove any difficulty that may be caused by the incumbency of performing every obligatory prayer within its time. In this hadeeth, ʿAbdullah ibn ʿUmar (may Allah be pleased with them) reports that the Messenger of Allah ﷺ would join Maghrib and ʿIshaa’ if the trip was important, and he wanted to hasten the journey. The Prophet ﷺpermitted for the traveller to combine Dhuhr and ʿAsr, and Maghrib and ʿIshaa’ [together] at the time of either of them; and to do the accompanying prayer with it – as mentioned in [the following] hadeeth narrated by Muslim, on the authority of Muʿaadh ibn Jabal (may Allah be pleased with him): “The Messenger of Allah ﷺ joined the Dhuhr and ʿAsr prayers, as well as Maghrib and ʿIshaa’ during the expedition of Tabuk.” There are two ways to join between two consecutive prayers, depending on what is easier [at the time and situation at hand: First - Combining by bringing the [second] prayer forward: It is to perform the ʿAsr prayer with Dhuhr, during the time of afternoon prayer (Dhuhr); and ʿIshaa’ with Maghrib during the time for the sunset prayer (Maghrib). Second - Combining by delaying the [first] prayer: It is to perform the Dhuhr prayer with ʿAsr, during the time of the mid-afternoon prayer (ʿAsr); and Maghrib with ʿIshaa’, during the time for the night prayer (ʿIshaa’). This is all with shortening the prayers that consist of four units to two while traveling. So, the prayer is shortened and combined, while Maghrib is not shortened, and Fajr is performed separately, and is not joined with any of the others. Likewise, there is no joining between ʿAsr and Maghrib. Whoever combines two prayers, it is necessary for him to not have a long period of time separating the performance of the two prayers, respectively. If there is a long separation between the two, he does not join them, and must pray the [second] prayer during its own time. From the other benefits that we can conclude from this hadeeth is noting the easiness that the Islamic Law makes for Muslims in their acts of worship..
