“On the Day you will see the believing men and believing women, their light streaming before them and to their right: ‘Good news for you today: gardens beneath which rivers flow, abiding therein forever. That is the supreme triumph.’” (12)
“Who is it that will lend Allah a goodly loan, so that He may multiply it for him, and he will have a noble reward? On the Day you will see the believing men and believing women, their light streaming...” That is, upon the Sirat (the Bridge). “Before them and to their right”: that is, on their right. Some said that it refers to all their sides, with a part being mentioned to denote the whole; and this light will guide them to Paradise.
Qatada said: We were informed that the Prophet, peace and blessings be upon him, said: “Among the believers are those whose light will shine from Medina to Aden of Abyan and Sanaa, and for lesser distances than that, until there are among the believers those whose light will illuminate only the spot at their feet.” (1)
