In the name of Allah, Most Gracious, Most Merciful.
Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (May Allah exalt his mention and protect him from imperfection) said: “He who believes in Allah and the Last Day, let him be hospitable to his guest; and he who believes in Allah and the Last Day, let him maintain good the ties of blood relationship; and he who believes in Allah and the Last Day, must speak good or remain silent”. (Al-Bukhari and Muslim)
Commentary: This hadith is mentioned here to highlight the importance of kindness to relatives. It enjoins considerate treatment to relatives and stresses that one should maintain relationship with them at all costs. So much so that even if they misbehave and sever relations with him, one should make efforts to restore not only relationship with them but also their rights. This is what kindness to relatives really means. Islam has laid great stress on it. Relatives include both paternal and maternal relatives.
