3 words to say at the end of your salah

اللَّهُمَّ أَعِنِّي عَلَى ذِكْرِكَ ، وَشُكْرِك ، وَحُسْنِ عِبَادَتِكَ

Allaahumma a‛innee ‛alaa dhikrika, wa shukrika, wa ḥusni ‛ibaadatik

The messenger of Allah (may the peace and blessings of Allah be upon him) said to Mu’adh ibn Jabal (may Allah be pleased with him): O Mu’adh, verily, by Allah I do love you, (therefore) do not forget to say at the end of each prayer (after tashahhud):

“O Allah, help me to remember You, to thank You, and to worship You in the best of manners.”
