IBNMAJAH 3660:
from Abū Hurayrah —
Messenger of Allah said: "Qintar is twelve thousand 'Uqiyah, each 'Uqiyah of which is better than what is between heaven and earth." And the Messenger of Allah ﷺ said: "A man will be raised in status in Paradise and will say: 'Where did this come from?' And it will be said:'From your son's praying for forgiveness for you.'"
ابن ماجة ٣٦٦٠:
عن ابو هريره —
عَنِ النَّبِيِّ ﷺ قَالَ الْقِنْطَارُ اثْنَا عَشَرَ أَلْفَ أُوقِيَّةٍ كُلُّ أُوقِيَّةٍ خَيْرٌ مِمَّا بَيْنَ السَّمَاءِ وَالأَرْضِ وَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الرَّجُلَ لَتُرْفَعُ دَرَجَتُهُ فِي الْجَنَّةِ فَيَقُولُ أَنَّى هَذَا فَيُقَالُ بِاسْتِغْفَارِ وَلَدِكَ لَكَ
