Is shaking hands with the opposite sex haram?

Who counts as a mahram

The ruling turns on a single distinction: whether the person is a mahram (someone a man may never marry, by blood, breastfeeding or marriage) or an ajnabiyyah (a woman outside that circle).

• Mahram — permitted: a man may shake hands with his wife, mother, sister, daughter, aunt or other mahram. Shaykh Ibn Baz states plainly that there is no harm in this.
• Non-mahram — prohibited: everyone else. This includes relatives people often treat casually — a brother's wife, a paternal or maternal uncle's wife, a cousin. Al-Tuwayjiri notes that a brother is not a mahram to his brother's wife, so she is like any other non-mahram woman to him.

The evidence the scholars rely on

Two narrations carry the ruling, one from the Prophet's ﷺ own words and one from his practice.

"I do not shake hands with women."— Sunan al-Nasa'i and Sunan Ibn Majah, from Umaymah bint Ruqayqah

"By Allah, the hand of the Messenger of Allah ﷺ never touched the hand of a woman; he used to pledge them only with words."— Sahih al-Bukhari 2713, from Aisha رضي الله عنها

Shaykh al-Albani points out that these are two separate proofs: one from what the Prophet ﷺ said, one from what he did. Aisha's report establishes his practice across the pledges of allegiance, and his own words state the principle directly.

Why the scholars call it prohibited, not merely disliked

The reasoning is not that desire is assumed present, but that the contact itself is a means to harm. Shaykh Ibn Baz explains that shaking hands is one of the wasail al-sharr — the pathways that lead to evil — and Shaykh al-Fawzan says the touching of a man and a woman stirs temptation and causes harm between them.

Shaykh Ibn Uthaymeen adds a point that closes the common objection about age: even an elderly woman is not exempt, because "for every fallen thing there is one who picks it up" — her years may be many, but her flesh is still that of a woman, and temptation can occur. He also notes that the temptation in shaking hands may be stronger than the temptation in looking.

The objection about intention

Shaykh Ibn Uthaymeen was asked directly about a man whose heart holds no improper purpose. His answer is that the ruling does not hinge on the state of the heart: it is not permitted to shake a non-mahram woman's hand, whether directly or through a barrier, whether she is a close relative who is not a mahram or a stranger. He describes the custom of shaking hands with a cousin as a reprehensible habit that must be discouraged.

The one reported concession

IslamWeb records that some scholars permitted shaking hands with an elderly woman who is not desired, citing the Hanafi and Hanbali position as stated in al-Hidayah — on the condition that one is safe from temptation. The Maliki and Shafi'i schools, by contrast, prohibit touching a non-mahram woman without distinguishing between a young woman and an old one.

IslamWeb's own conclusion, however, is that the preponderant view is prohibition — especially in an age when hearts have hardened and morals have decayed. This is also the position of the contemporary scholars quoted above, who make no exception for age.

What to do instead

The scholars do not leave you without an alternative. Shaykh Ibn Baz describes the proper exchange: greet with words — "as-salamu alaykum", "how are you", "how are your children" — good speech without any handshake. He notes that the Prophet ﷺ spoke with women and they spoke with him, and that a conversation free of desire, conducted with modesty and distance, carries no blame.

If refusing a hand creates awkwardness, the ruling still stands; the scholars treat the custom itself as the thing to be corrected, not accommodated.

Key takeaways

• Shaking hands with a non-mahram of the opposite sex is not permitted, by the agreement of the contemporary scholars cited here.
• The prohibition applies regardless of age, intention, or whether a barrier is present.
• Mahram relatives — spouse, parents, siblings, children, aunts and uncles — are exempt.
• Relatives by marriage such as a brother's wife or a cousin remain non-mahram and are covered by the prohibition.
• A verbal greeting with modest, purposeful speech is the permitted alternative.
