لَقَدْ مَنَّ اللّهُ عَلَى الْمُؤمِنِينَ إِذْ بَعَثَ فِيهِمْ رَسُولاً مِّنْ أَنفُسِهِمْ يَتْلُو عَلَيْهِمْ آيَاتِهِ وَيُزَكِّيهِمْ وَيُعَلِّمُهُمُ الْكِتَابَ وَالْحِكْمَةَ وَإِن كَانُواْ مِن قَبْلُ لَفِي ضَلالٍ مُّبِينٍ
﴿١٦٤﴾
سورة آل عمران
(3/164) Certainly Allah confers a Blessing (the Spirit of the Imam of the Time) upon (the heads of) the believers when He sends in them a Messenger from among themselves. He explains to them His Verses and cleanses them and teaches them the Book and Wisdom, while before that (before wishing to reach Allah) they were indeed in a manifest Misguidance.
Surah Al Imran
