عن ثوبان رضي الله عنه قال سمعت رسول الله صلى الله عليه و سلم يقول طوبى للمخلصين أولئك مصابيح الهدى تنجلي عنهم كل فتنة ظلماء رواه البيهقي (الترغيب و الترهيب 1/59)
It is narrated from Hadhrat Thaubaan (Radhiyallahu Anhu) that he heard Rasulullah (Sallallahu Alayhi Wasallam) saying: “Glad tidings of Paradise be for the Mukhliseen (i.e. those who possess the wealth of ikhlaas.) Certainly they are beacons of light and guidance in the Ummah. It is on account of them that every dark fitna (trial and tribulation engulfing the Ummah) is lifted.
