It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Allah Almighty has, among His creation, some chosen servants whom He keeps alive in well-being, and when He takes them in death to His Paradise. They are the ones over whom tribulations pass like pieces of the dark night, while they remain in well-being from Allah in the midst of them."
