When entering the market

Lā ilāha illallāh waḥdahu lā sharīka lah, Lahu ‘l-mulku wa lahu ‘l-ḥamd, Yuḥyī wa yumīt, wa huwa ḥayyun lā yamūt, Biyadihi ‘l-khayr, wa huwa `alā kulli shay'in Qadīr. None has the right to be worshipped but Allah alone, Who has no partner. His is the dominion and His is the praise. He brings life and He causes death, and He is living and does not die. In His Hand is all good, and He is Able to do all things. Reference: At-Tirmidhi 5/291, and Al-Hakim 1/538. Al-Albani graded it good in Sahih Ibn Majah 2/21 and Sahih At-Tirmidhi 3/152.
