Z'KIR REWARD OF 40 MILLION GOOD DEEDS..

Fourty million good deeds
Tamim Ad-Dari (may Allah be pleased with him) narrated that:
 
The Messsenger of Allah (ﷺ) said: “Whoever says ten times:

 ‘Ash-hadu an lā ilāha illallāh, waḥdahu lā sharīka lahu, ilahan wahidan, aḥadan ṣamadan lam yattakhidh ṣāḥibatan wa lā waladan wa lam yakun lahu kufuwan aḥad,’ 
 

(I bear witness that none has the right to be worshipped but Allah. Alone, without partner, One Deity, the One, As-Samad, He did not take a wife, nor a child, nor is there anyone like Him)’ 

 
Allah will write for him forty million good deeds.”
