Al-Matalib al-'Aliyah 2546 — Kindness to parents

It is narrated from Sayyiduna Sa'sa'ah (may Allah be pleased with him): I came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah, to whom should I be most kind and dutiful?" He (peace and blessings be upon him) said: "To your mother, your father, your sister, your brother, then whoever is nearest to you (in kinship), then whoever is nearest after that."
Imam Abu Ya'la recorded this hadith in his Musnad; its chain contains Iqal bin Shabah and his father, regarding whose reliability there is criticism; however, its text is strengthened by supporting reports from other authentic and sahih hadith.
