Hadith record

Hadith.2588 - Imam Jafar ibn Muhammad Al-Sadiq (as) said: "If you have intercourse with your spouse after entering the state of Ihram but before reciting the Talbiyah, there is nothing upon you. If you have intercourse while in the state of Ihram before standing at al-Mash'ar, you must offer a camel as a sacrifice and repeat the Hajj in the following year. If you have intercourse after standing at al-Mash'ar, you must offer a camel, but repeating the Hajj is not required. If you do so out of forgetfulness, negligence, or ignorance, there is nothing upon you."
