Tradition 16

اَوّلُ ما يُحاسَبُ بِهِ العَبدُ اَلصّلاةُ فَاِن قُبِلَت قُبِلَ ما سِواها

Imam al-Baqir (‘a) said: “On the Reckoning Day, the first thing that a servant will be reckoned for is the prayer; therefore, if it is accepted, the rest (good actions) will be accepted, too, (otherwise, his other good deeds will not avail him).”
