The Messenger of Allah ﷺ said, "When one of you performs ablution, let him put water into his nose and then blow it out. Whoever cleans himself with stones, let him use an odd number. And when one of you wakes from sleep, let him wash his hand before dipping it into the water of his ablution, for none of you knows where his hand has spent the night."
حدثنا عبد الله بن يوسف قال أخبرنا مالك عن أبي الزناد عن الأعرج
أن رسول الله ﷺ قال إذا توضأ أحدكم فليجعل في أنفه ثم لينثر ومن استجمر فليوتر وإذا استيقظ أحدكم من نومه فليغسل يده قبل أن يدخلها في وضوئه فإن أحدكم لا يدري أين باتت يده
