Hawzah News Agency – Imam Baqir peace be upon him says:

صِلَةُ الأرحامِ تُزَكِّي الأعمالَ وتُنْمِي الأموالَ، وتَدفَعُ البَلوى‏، وتُيَسِّرُ الحِسابَ وتُنسِئُ في الأجَلِ.

'Maintaining relations with one's kin purifies one's actions, brings about an increase in wealth, repels misfortunes, eases the account [on the Day of Resurrection], and delays one's appointed time of death.'
