Sahl bin `Abdullah said, “There is no veil between the servant and Allah thicker than making claims, nor a path that one takes to Him nearer than that of displaying need; and the source of all good in this life and the hereafter is fear of Allah.” What proves that is Allah’s statement:
“And when the anger of Musa subsided, he took up the tablets; and in their inscription was guidance and mercy for those who are fearful of their Lord.”[Al-A`raf 7:154]
Thus He has informed us that guidance and mercy are for those who fear Allah.
[Majmu` al-Fatawa, Ibn Taymiyyah (17/20)]
أصل كل خير في الدنيا والآخرة
