أَسْتَوْدِعُ اللَّهَ دِينَكَ، وَأَمَانَتَكَ، وَخَوَاتِيمَ عَمَلِكَ

I leave your religion in the care of Allah, as well as your safety, and the last of your deeds.

'Astawdi'ullaaha deenaka, wa 'amaanataka, wa khawaateema 'amalika.

Ahmad 2/7, At-Tirmithi 5/499. See also Al-Albani, Sahih At-Tirmithi 2/155.
