Hadith 17:134
Abu Mu'awiyah narrated to us, from al-A'mash, from al-Raqashi, from Anas, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Whoever has two daughters or two sisters and treats them well as long as they accompany him, he and I will be in Paradise like these two," meaning the index finger and the middle finger.
حدثنا أبو معاوية عن الأعمش عن الرقاشي عن أنس قال قال رسول الله صلى الله عليه وسلم من كان له ابنتان أو أختان فأحسن إليهما ما صحبتاه كنت أنا وهو في الجنة كهاتين يعني السبابة والوسطى
