73.1 . O thou wrapped up in thy raiment!

73.2 . Keep vigil the night long , save a little

73.3 . A half thereof , or abate a little thereof

73.4 . Or add ( a little ) thereto and chant the Quran in measure ,

73.5 . For We shall charge thee with a word of weight .

73.6 . Lo! the vigil of the night is ( a time ) when impression is more keen and speech more certain .

73.7 . Lo! thou hast by day a chain of business .

73.8 . So remember the name of thy Lord and devote thyself with a complete devotion

73.9 . Lord of the East and the West ; there is no God save Him ; so choose thou Him alone for thy defender

73.10 . And bear with patience what they utter , and part from them with a fair leave taking .

73.11 . Leave Me to deal with the deniers , lords of ease and comfort ( in this life ) ; and do thou respite them awhile .

73.12 . Lo! with Us are heavy fetters and a raging fire ,

73.13 . And food which choketh ( the partaker ) , and a painful doom

73.14 . On the day when the earth and the hills rock , and the hills become a heap of running sand .

73.15 . Lo! We have sent unto you a messenger as witness against you , even as We sent unto Pharaoh a messenger .

73.16 . But Pharaoh rebelled against the messenger , whereupon We sealed him with no gentle grip .

73.17 . Then how , if ye disbelieve , will ye protect yourselves upon the day which will turn children grey ,

73.18 . The very heaven being then rent asunder . His promise is to be fulfilled .

73.19 . Lo! This is a Reminder . Let him who will , then , choose a way unto his Lord .

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 .
