15 – Hammād narrated from Ibrāhīm, from someone whom I do not suspect, from Abū Saʿīd al-Khudrī and Abū Hurayrah (may Allah be pleased with them), that the Prophet ﷺ said:

“A man must not bid against his brother’s bargaining, nor marry a woman who is already the object of his brother’s proposal. A woman is not to be married together with her paternal or maternal aunt, and a woman must not ask for her sister to be divorced so as to overturn what is in her bowl—for Allah is her Provider. Do not conduct sales determined by the casting of stones, and when you hire a worker, inform him of his wage.”
