Distance and estrangement from the wife: its ruling and its harms

He says: What is the ruling in Islam regarding distancing oneself from one’s wife for a year or two?
Answer: It is not permissible for a Muslim to boycott his wife in terms of sexual intercourse, because this harms her and may lead to her falling into something with no good outcome. Therefore, it is obligatory for him to have intercourse with her in a good manner, according to his ability and capacity. Some scholars said that it is obligatory for him to do so once every four months, but that is not clear from the perspective of evidence. Rather, it is obligatory for him to treat her with kindness, as Allah the Exalted said: [Surat al-Nisa: 19], and He the Glorious and Exalted said: [Surat al-Baqarah: 228].
Treating her with kindness includes having intercourse with her, being affectionate with her, speaking to her in the best manner, providing her with the necessary financial maintenance, and so on. It is not part of kindness to boycott her for such a long period. Therefore, it is obligatory for him to seek her permission; if she consents and permits it, there is no blame on him. Otherwise, it is obligatory for him to care for her and have intercourse with her in a good manner, according to his ability and capacity, and according to what he sees as sufficient to prevent either of them from falling into what is not approved. Indeed, intercourse protects both him and her, and neglecting her for a long period poses a danger to both of them, except in cases of a valid legal excuse, such as illness or travel required for seeking knowledge, seeking a livelihood, or similar obstacles.
