What to say after completing the prayer

اللَّهُمَّ إِنِّي أَسْأَلُكَ عِلْماً نافِعاً، وَرِزْقاً طَيِّباً، وَعَمَلاً مُتَقَبَّلاً

Allāhumma innī asʾaluka ʿilman nfiʿan, wa rizqan ṭayyiban, wa ʿamalan mutaqabbalā

O Allah, I ask You for knowledge which is beneficial and sustenance which is good, and deeds which are acceptable.
