Strain not thine eyes. (Wistfully) at what We have bestowed on certain classes of them, nor grieve over them: but lower thy wing (in gentleness) to the believers. 15:88
Hadith of the day
Seventy thousand angels worship near the grave of Imam Husayn (a). The prayer (salah) of one of them, is equal to a thousand prayers of mankind. The reward of this prayer is for the visitors of Imam Husayn's (a) grave. The curse of God, His angels and all mankind is forever upon the killers of Imam Husayn (a).
