73.11 . Leave Me to deal with the deniers , lords of ease and comfort ( in this life ) ; and do thou respite them awhile .
73. 73.12 . Lo! with Us are heavy fetters and a raging fire ,
73. 73.13 . And food which choketh ( the partaker ) , and a painful doom
73. 73.14 . On the day when the earth and the hills rock , and the hills become a heap of running sand .
73. 73.15 . Lo! We have sent unto you a messenger as witness against you , even as We sent unto Pharaoh a messenger .
73. 73.16 . But Pharaoh rebelled against the messenger , whereupon We sealed him with no gentle grip .
73. 73.17 . Then how , if ye disbelieve , will ye protect yourselves upon the day which will turn children grey ,
73. 73.18 . The very heaven being then rent asunder . His promise is to be fulfilled .
73. 73.19 . Lo! This is a Reminder . Let him who will , then , choose a way unto his Lord .
73. 73.20 . Lo! thy Lord knoweth how thou keepest vigil sometimes nearly two thirds of the night , or ( sometimes ) half or a third thereof , as do a party of those with thee . Allah measureth the night and the day . He knoweth that ye count it not , and turneth unto you in mercy . Recite , then , of the Quran that which is easy for you . He knoweth that there are sick folk among you , while others travel in the land in search of Allah ' s bounty , and others ( still ) are fighting for the cause of Allah . So recite of it that which is easy ( for you ) , and establish worship and pay the poor due and ( so ) lend unto Allah a goodly loan . Whatsoever good ye send before you far your souls , ye will surely find it with Allah , better and greater in the recompense . And seek forgiveness of Allah . Lo! Allah is Forgiving , Merciful .
