I intended to prohibit suckling during pregnancy (ghailah), but I considered the Greeks and the Persians and saw that they practiced it, without any injury being caused to their children thereby. Malik said : Ghailah means that a man has intercourse with a women while she is suckling a child.
Sunan Abi Dawud Book 29, Hadith 28
← Previous Hadith I heard the Messenger of Allah (ﷺ) as saying: Do not kill your children secretly, for the milk, with which a child is suckled while his mother is pregnant, overtakes the horseman and throws him from his horse.

Sunan Abi Dawud Book 29, Hadith 27 Next Hadith → Zaynab, the wife of Abdullah ibn Mas'ud, told that Abdullah said: I heard the Messenger of Allah (ﷺ) saying: spells, charms and love-potions are polytheism.

I asked: Why do you say this? I swear by Allah, when my eye was discharging I used to go to so-and-so, the Jew, who applied a spell to me. When he applied the spell to me, it calmed down. Abdullah said:

That was just the work of the Devil who was picking it with his hand, and when he uttered the spell on it, he desisted. All you need to do is to say as the Messenger of Allah (ﷺ) used to say: Remove the harm, O Lord of men, and heal. Thou art the Healer. There is no remedy but Thine which leaves no disease behind.
