Riyad as-Salihin 6:31

Usamah bin Zaid (May Allah be pleased with them) reported:

A daughter of the Prophet (ﷺ) sent a message to him that her son was at his last breath, and requested him to come to her. The Messenger of Allah (ﷺ) sent back the informer saying: "To Allah belongs what He takes and what He gives, and everything has a limited period (in this world). So ask her to endure patiently, and expect the reward of Allah." [Al-Bukhari and Muslim] .
