Allah say in the Holy Qur'an: “Allah keeps firm those who believe, with the firm word, in worldly life and in the Hereafter. And Allah sends astray the wrongdoers. And Allah does what He wills.” [Ibrahim 14:27]
{يُثَبِّتُ اللَّـهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ ۖوَيُضِلُّ اللَّـهُ الظَّالِمِينَ ۚوَيَفْعَلُ اللَّـهُ مَا يَشَاءُ}

They answered that God and his Messenger Know better. He said: 'it is revealed to tell about the torment of the unbeliever in his grave. By God, ninety nine dragons are assigned for him, do you know what a dragon is! It consists of ninety nine snakes, each snake has seven heads that bite and snap him till the Day of Judgment''. [Approved by al-Albany]
«أتدرون فيما أنزلت هذه الآية {فَإِنَّ لَهُ مَعِيشَةً ضَنكًا وَنَحْشُرُهُ يَوْمَ الْقِيَامَةِ أَعْمَىٰ}؟! ، قال : أتدرون ما المعيشة الضنكة ؟ . قالوا : الله ورسوله أعلم ! قال : عذاب الكافر في قبره ! والذي نفسي بيده ؛ إنه يسلط عليه تسعة وتسعون تنينا – أتدرون ما التنين ؟ سبعون حية ، لكل حية سبع رؤوس – يلسعونه ويخدشونه إلى يوم القيامة»
