Hazrat Ibn Abbas (may Allah be pleased with them both) regarding the saying of Allah Almighty, "So when the trumpet will be blown," states that the Messenger of Allah (peace and blessings be upon him) said: How can I be at ease, while the one assigned to blow the trumpet has placed it in his mouth, has bent his forehead, and is listening attentively, waiting for when he will be commanded to blow the trumpet? The companions of the Prophet (peace and blessings be upon him) asked: Then how should we supplicate? The Prophet (peace and blessings be upon him) said: You should recite these words: Allah is sufficient for us, and He is the best disposer of affairs, and we have placed our trust in Allah alone.

Hazrat Sha'bi narrates that Hazrat Abdullah bin Amr (may Allah be pleased with him) said: When Ibrahim was thrown into the fire, he recited these words: Allah is sufficient for us and He is the best disposer of affairs.

Hazrat Abu Sinan narrates that Hazrat Saeed bin Jubair said: Placing trust in Allah is the foundation of faith.
