An endeavour for the sake of Allah

عَنْ أَنَسِ بْنِ مَالِكٍ رَضِىَ اللهُ عَنْهُ عَنِ النَّبِىِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ

لَغَدْوَةٌ فِى سَبِيْلِ اللهِ أَوْ رَوْحَةٌ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيْهَا

Hazrat Anas bin Malik^ra narrated that the Holy Prophet^sa said, “A single endeavour for the sake of Allah in the forenoon or in the afternoon is better than the world and whatever is in it.”
