Entrusting Oneself to Allah
The one who entrusts his affair to Allah is in eternal rest and constant carefree ease of life; he is above caring about anything except Allah, as the Commander of the Faithful said, I was content with what Allah allotted me, and I entrusted my affair to my Creator. As Allah was good in what has passed, so He will be good in what remains.
As Allah said, in the words of a believer among the people of Pharaoh,
وَأُفَوِّضُ أَمْرِي إِلَى اللَّهِ إِنَّ اللَّهَ بَصِيرٌ بِالْعِبَادِ. فَوَقَاهُ اللَّهُ سَيِّئَاتِ مَا مَكَرُوا وَحَاقَ بِآلِ فِرْعَوْنَ سُوءُ الْعَذَابِ
The Arabic word for entrustment (tafwid) consists of five letters, each letter having an injunction. He who heeds their commands brings the ta of his abandoning (tark) plans in this world; the fa of the annihilation (fana) of every aspiration other than Allah; the waw of fulfilling (wafa) the contract and confirming the promise; the ya of despairing (ya's) of yourself, and certainty (yaqin) in your Lord; and the dad of a conscience (damir) which is purely for Allah, and of the need (darurah) for Him. He who entrusts everything to Allah wakes up in the morning free of all evils, and at night sleeps protected in his faith.
