Al-Hasan reported: Umar, may Allah be pleased with him, used to say, “O Allah, make my deeds righteous, make them purely for Your sake, and do not let anyone else have a share of them.”

عَنِ الْحَسَنِ أَنَّ عُمَرَ رضي الله عنه كَانَ يَقُولُ اللَّهُمَّ اجْعَلْ عَمَلِي صَالِحًا وَاجْعَلْهُ لَكَ خَالِصًا وَلَا تَجْعَلْ لِأَحَدٍ فِيهِ شَيْئًا
