Hadith 6:1285
Waki’ narrated to us, Ibn Abi Rawwad narrated to us, Sharik narrated to us, from al-Hajjaj ibn Dinar, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Indeed, from the righteousness after righteousness is that you pray for them along with your prayer, and that you fast on their behalf along with your fasting, and that you give charity on their behalf along with your charity."
