Excessive Prayer And Fasting Of Imam Husayn (‘A)

His Eminence (‘a) was mostly engrossed in prayers and fasting. ¹ Every twenty hours he used to recite a thousand units of prayer as narrated by his son, Zainul Abideen. ²
In the month of Ramadan he used to complete the recitation of Quran. ³ Ibn Zubair has mentioned about the Imam’s worship saying: “By Allah they killed him! The one who used to stand up in prayers at night and fasted during the days too much.” ^{4 5}
