Hazrat Abu Zar(RA) narrates that Rasoolullah (Sallallaahu Alaihi Wasallam) said to me: be regular in the recitation of the Quran and in making the zikr of Allah Ta'ala; by means of these actions you will be mentioned in the sky (by Allah Ta'ala and the Angels) and you will receive Nur (light of guidance) on the earth. [Baihaqi]
