From every disease except poisoning. Qatada said: Every day he takes twenty-one pills and puts them in a piece of cloth to soak it. So he squirts two drops with it every day in his right nostril, and in the left nostril, and the second in the left nostril with two drops, and in the right nostril a drop, and the third in the right. Two drops, and one drop on the left.
