If I pray and my breath smells bad, is my prayer valid?

The worshipper communes with his Lord, thus he must be prepared for this communion by ensuring the cleanliness of his body, clothes, and place, as Allah Almighty says: (O Children of Adam, take your adornment at every place of prayer). Prayer with the presence of a foul odor is valid but disliked. If the odor is in the mosque and harms the worshippers and the angels, then it is forbidden, as the Prophet, peace and blessings be upon him, said: (Whoever eats from this plant – meaning garlic – let him not approach our mosque). The advice is to take care of oral hygiene and treat any problem that causes odor.
