Anas reported God’s Messenger as saying that if anyone asks God for paradise three times, paradise will say, ‘‘O God, bring him into paradise;” and if anyone asks for protection from hell three times, hell will say, "O God, grant him protection from hell.” Tirmidhi and Nasa’i transmitted it.

وَعَنْ أَنَسٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:

مَنْ سَأَلَ اللَّهَ الْجَنَّةَ ثَلَاثَ مَرَّاتٍ قَالَتِ الْجَنَّةُ: اللَّهُمَّ أَدْخِلْهُ الْجَنَّةَ وَمَنِ اسْتَجَارَ مِنَ النَّارِ ثَلَاثَ مَرَّاتٍ قَالَتِ النَّارُ: اللَّهُمَّ أَجِرْهُ مِنَ النَّارِ

رَوَاهُ التِّرْمِذِيُّ وَالنَّسَائِيّ
