الْمُقَدِّمُ
AL-MUQADDIM
(The Expediting One)
The Expediter, The Promoter, The One who puts things in their right places.
Allah is Al-Muqaddim, The One who promotes or brings forward. This include promoting his servants to higher ranks providing rich rewards.
From the root q-d-m which has the following classical Arabic connotations: to precede, to come before to head, to lead to offer, to bring forward to make foremost, to put at the front to advance, to promote to exist without beginning
Ali (r) reported that when the Prophet (s) prayed, the last thing he would say between the tashahud and the tasleem was, "O Allah, forgive my past and later sins, what was in private and what was in public, and what I have been extravagant in. You are more knowledgeable of it than I. You are the Promoter and the Retarder. There is no god except You." (Related by Muslim.)
