SubhanAllah, Allah Says, if You Are Gracious, I Will Increase You.

The Prophet Salaam said he calls upon Allah and he says, My Lord, My Lord. He sustains himself with everything that is haram,. But then he says, Yaraab, give me. SubhanAllah: It may be that Allah still responds to some people's du'as despite them being in that condition but it certainly won't be because they are in that condition.
