Abu Hurayrah reported that a desert A'rab came to the Prophet(saws) and said 'Guide me to an action which if I
do will certainly take me to Paradise' He (saw) replied with several matters of which the first was "You shall worship Allah
and not make shirk with him in anything...." (BUKHAARI, MUSLIM)
Abu Hurayrah reported that the Prophet(saws) said
"Imaan has got seventy-odd branches the highest of which is to affirm Laa ilaaha ill Allah and the lowest of which is
to remove something harmful from the road and modesty is part of Imaan" (BUKHAARI, MUSLIM, IBN MAAJAH, ABU DAWOOD)
Allah (swt) says "Whosoever rejects Imaan then
fruitless are his actions and in the hereafter he will be among the losers" (al Maai’dah 5:5)
"But anyone who does righteous actions,
being a believer, need fear no wrong nor any unjust injury." (Ta Ha 20:112)
Allah (swt) says "And it has been revealed to you as it was to those before you ‘If you commit shirk
with Allah surely all your deeds will be in vain and you will certainly be amongst the losers." (az Zumar 39:65)
