'Aishah (May Allah be pleased with her) reported:
Messenger of Allah (ﷺ) said, "The bond of relationship is suspending from the Throne, and says: 'He who keeps good relations with me, Allah will keep connection with him, but whosoever severs relations with me, Allah will sever connection with him".

[Al-Bukhari and Muslim].
