617. hadíth
وَ فِي خَبَرٍ آخَرَ: "إِنَّ صَلاَتَهُ تُوقَفُ بَيْنَ اَلسَّمَاءِ وَ اَلْأَرْضِ فَإِذَا تَابَ رُدَّتْ عَلَيْهِ وَ قُبِلْتُ مِنْهُ".
And in another narration: "Indeed, his prayer will be suspended between the sky and the earth. But if he repents, it will be returned to him and accepted from him."
