It is narrated from Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever gives respite to someone in hardship, or makes things easy for him, Allah will shade him in His shade on the Day when there is no shade but His shade."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ubaydah except al-Fadl bin Musa, and it is narrated from Ka'b bin Ujrah (may Allah be pleased with him) only with this chain."
