وَالَّذِينَ آمَنُوا وَاتَّبَعَتْهُمْ ذُرِّيَّتُهُم بِإِيمَانٍ أَلْحَقْنَا بِهِمْ ذُرِّيَّتَهُمْ (And those who believed and their children followed them in belief, We will join their children with them,... 52:21) Sayyidna Ibn 'Abbas ؓ reports from the Holy Prophet ﷺ who said:
"Verily, Allah elevates the ranks of the believers' children to the rank of their parents, even though the latter do not deserve the same rank as their parents deserve, so that the eyes of the parents are comforted." (Hakim, al-Baihaqi in his Sunan, al-Bazzar, Abu Nu'aim in al-Hilyah, ibn-Jarir and ibn-Abi Haim as quoted by Mazhari [ Tr.])
In the Hereafter, it will not happen that one man’s sins are attributed to another, and nobody will be able to enter Paradise except on the basis of his faith and his own righteous deeds. But, the occupants of Paradise will be given one special privilege: if parents are in a high stratum of Paradise and their children in some other stratum, the children will be united with their parents so that their happiness should increase. Only one who, in spite of being among his wife and children, has always been moved by the fear of God and who linked his hopes and fears with the one and only God, will be entitled to enter the sublime world of Paradise.
