Did the Prophet (peace be upon him) feel distressed, and repeat: "O Living, O Sustainer, by Your mercy I seek aid"?

When the Prophet, peace and blessings be upon him, was afflicted by distress or anxiety, he would say: "O Living, O Sustaining, by Your mercy I seek aid." This is due to the special effect of the two names "Al-Hayy (the Living)" and "Al-Qayyum (the Sustaining)" in dispelling distress and answering prayers. The attribute of life encompasses all attributes of perfection, and the attribute of sustained existence encompasses all attributes of actions. It has been said that Allah's Greatest Name is Al-Hayy Al-Qayyum.
