It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) was asked about the food of the believers in the time of the Dajjal, and he (peace and blessings be upon him) said: "The food of the angels." The Companions said: What is the food of the angels? He (peace and blessings be upon him) said: "Their speech is glorification (tasbih) and sanctification (taqdis). So whoever's speech on that day consists of glorification and sanctification, Allah Almighty will remove the severity of hunger from him, and he will have no fear of hunger." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.
