Imam Bukhari rahmahullah ne kaha Quran mein jo «khairun uqba» aaya hai to «aaqibah» aur «uqub» ke ek hi maani hain jin se aakhirat murad hai.

Hum se Sulayman bin Harb ne bayan kiya, unhon ne kaha hum se Hammad bin Zayd ne bayan kiya, in se Abu Ayub Sakhtiyani ne bayan kiya, in se Abu Usman Nahdi ne aur in se Abu Musa Ash'ari razi Allahu anhu ne bayan kiya ke hum Nabi Karim salla Allahu alaihi wasallam ke saath ek safar mein thay jab hum kisi buland jagah par charhte to takbeer kehte. Nabi Karim salla Allahu alaihi wasallam ne farmaya ”logo! apne oopar raham karo, tum kisi behre ghaib Rabb ko nahi pukarte ho tum to is zaat ko pukarte ho jo bahut zyada sunne wala, bahut zyada dekhne wala hai.“ Phir Nabi Karim salla Allahu alaihi wasallam mere paas tashreef laaye. Main is waqt zer-e-lab keh raha thu «laa haula wa laa quwwata illaa billaah» Nabi Karim salla Allahu alaihi wasallam ne farmaya ”Abdullah bin Qays kaho «laa haula wa laa quwwata illaa billaah» kyunke yeh jannat ke khazanon mein se ek khazana hai“ ya Nabi Karim salla Allahu alaihi wasallam ne yeh farmaya ”main tumhein ek aisa kalma na bata doon jo jannat ke khazanon mein se ek khazana «laa haula wa laa quwwata illaa billaah» hai.“
