Accordingly, we say: if the right‐hand side of the row is farther away while the left‐hand side is clearly nearer, then the left side is preferable to the right because it is closer to the imam. Furthermore, when people first prayed in groups of three—an imam with two followers—one would stand to his right and the other to his left; never were both placed on his right. This shows that nearness to the imam and having him centered among the worshipers were both taken into account.
That earlier arrangement—where the imam and two others formed a single line—was later abrogated, and now, if two pray with the imam they line up behind him. Still, the fact that, while the earlier practice was in force, he placed one on his right and the other on his left demonstrates that the right side is not unconditionally superior. It is only better than the left when the two sides are equal or nearly so; if the left enjoys a clear advantage, namely being closer to the imam, then the left side is superior.
In the report of the vision the Messenger of Allah (peace and blessings be upon him) related, he was using a siwak when two men approached him; he intended to hand it to the younger, but he was told, “Let the elder be first, let the elder be first.” This also shows that age is to be considered and that the elder is given precedence when handing something over.
Hence, when you serve food, coffee, or tea, do not begin from the right; start with the eldest person in front of you. When the Prophet (peace and blessings be upon him) was about to give it to the younger he was told, “Let the elder be first.” It is clear that had the younger been on the left, the Prophet would not have crossed over to give it to him; evidently the younger was on the right and the Prophet was about to observe the custom of beginning from the right, but he was directed to favor the elder instead. Therefore, if the people are directly in front of you, you start with the eldest, not with the right. Only when they are seated to your right and left do you begin with the right.
