Acting by the Command of Allah

قَالَ الِمَامُ مُحَمّدُ بْنُ عَلِيّ البَاقِرُ : يُوْحى إِلَيْهِ فَيَعْمَلُ بِالْوَحِِْيِ بِأَمْرِ الِّ.

Imam Muhammad ibn ‘Ali al-Baqir (peace be upon both of them) has said: “Revelation
(from Allah (awj)) will come to him (Imam al-Mahdi) and he will act according to the
revelation by the command of Allah.”
