ذَهَبَ الظَّمَأُ وَابْتَلَّتِ العُرُوقُ، وَثَبَتَ الْأَجْرُ إِنْ شَاءَ اللَّهُ

The thirst is gone, the veins are moistened and the reward is confirmed, if Allah wills.

Thahabadh-dhama'u wabtallatil-'urooqu, wa thabatal-'ajru 'inshaa'Allaah.

Abu Dawud 2/306 and others. See also Al- Albani, Sahihul-Jami' As-Saghir 4/209.
