Ja`far b. Muhammad b. Masrur narrated to us. He said: Al-Husayn b. Muhammad b. `Amer narrated to us from his uncle `Abdullah b. `Amer from Muhammad b. Abi `Umayr from `Abdullah b. Sinan from al-Sadiq Ja`far b. Muhammad . He said:

The Messenger of Allah (s) prayed Fajr. When he finished, he turned his face toward his companions, and asked if a group of people had attended. So, they said: No, O Messenger of Allah. So, he said: Are they away (travelling)? They said: No. So, he said: There is no prayer that is harder on the hypocrites than this prayer and `Isha'.
