أَسْتَوْدِعُ اللَّهَ دِيْنَكَ وَأَمَانَتَكَ وَخَوَاتِيْمَ عَمَلِكَ

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

I leave your religion in the care of Allah, as well as your safety, and the last of your deeds. Abdullah ibn Umar (RA) said, The Messenger of Allah (ﷺ) said: when he bid farewell, he grab his hand and did musafaha and said the above mentioned dua.In another narration, Abdullah Ibn Yazid Khatmi (RA) said, The Messenger of Allah (ﷺ) bid farewell by saying these words. But in this case, he used plural (kum) instead of singular (ka): “Astad’iullaha diinaakum wa amaanatakum wa khawatima a’maalikum” I leave your religion in the care of Allah, as well as your safety, and the last of your deeds.
