As evidenced from a Mohammedan “Teshuvah” (via Wikipedia):
And if a man wants to take a concubine and his wife says to him “I will kill myself”, he is not prohibited [from doing so], because it is a lawful act, but if he abstains to save her grief, he will be rewarded, because of the hadith “Whoever sympathises with my community, God will sympathise with him.”
(A 17th-century Hanafi scholar, Imam Haskafi, writes in his jurisprudential work Al-Durr al-Mukhtar)
