It was narrated from Ibn 'Abbas (رضي الله عنه) that the Prophet (ﷺ) said:

"Whoever has two sisters and is kind to them whilst they are with him, will enter Paradise because of them." Muhammad bin 'Ubaid said: "Anyone who has two daughters and treats them kindly so long as they are with him, Allah, may He be exalted, will admit him to Paradise."
