Astaghfrullah! can you imagine that Allah(swt) will put his foot in hell fire. Allah(swt) told us again and again that refrain from hell fire, hell is bad place which is made for pagons but Allah will put his own foot on it, then hell fire will be filled.
The last part of hadith says that Allah will make a creation and fill the paradise with it. Is it justice of Allah that for us who spend whole life as a believer, suffered through difficulties and faced all tests and remained faithful, then earned paradise.But another creation will go in the same paradise with out difficulties of life?
