Patience is at the first stroke
إِنَّمَا الصَّبْرُ عِنْدَ الصَّدْمَةِ الْأُولَى
Innama-s-sabru inda-s-sadmati-l-ula.
"Patience is only at the first stroke."
Narrated by Anas ibn Malik. Sahih al-Bukhari 1283, Sahih Muslim 926
A short reflection
Said to a woman weeping at a grave. Crying later, sighing later, all of it is reasonable. The sabr that earns the reward is held in the instant the news arrives.
