And He guides towards Himself, one who inclines towards Him. [Ash Shura 42;13]
Hakeem ul Ummah Shaykh Ashraf Ali Thanwi (Raheemahullah) took an oath;
I swear by Allah Ta’ala that one who sincerely strives in search of Allah Ta’ala with all his heart will definitely find Him. Only that person will not find Allah Ta’ala who did not have a heartfelt longing and desire for Him.
Imam Fakhruddeen Razi (Raheemahullah) while explaining this verse in his Tafseer-e-Kabeer, cites a hadith-e-Qudsi,
“Who draws nearer to Me a hands span, I will draw nearer to him an arm’s length, and if he draws nearer to Me an arm’s length, I will draw nearer to him a fathom length, and if he comes to Me walking, I will rush to him at (great) speed” [Bukhari & Muslim]
