Sunan Ibn Majah, Volume 5, Book 33, Hadith 3670 (DarusSalam) ⓘ

It was narrated from Ibn Abbas that the Messenger of Allah said: "There is no man whose two daughters reach the age of puberty and he treats them kindly for the time they are together, but they will gain him admittance to Paradise."

حَدَّثَنَا الْحُسَيْنُ بْنُ الْحَسَنِ، حَدَّثَنَا ابْنُ الْمُبَارَكِ، عَنْ فِطْرٍ، عَنْ أَبِي سَعْدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ مَا مِنْ رَجُلٍ تُدْرِكُ لَهُ ابْنَتَانِ فَيُحْسِنُ إِلَيْهِمَا مَا صَحِبَتَاهُ أَوْ صَحِبَهُمَا إِلاَّ أَدْخَلَتَاهُ الْجَنَّةَ ‏" ‏ ‏.‏
