Sahih Muslim 1423
Sahih Muslim · Book 16: The Book of Marriage · It is recommended to get married and arrange marriages in Shawwal, and it is recommended to consummate the marriage in that month
وَحَدَّثَنَاهُ ابْنُ نُمَيْرٍ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا سُفْيَانُ ، بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ فِعْلَ عَائِشَةَ .
This hadith has been narrated on the authority of Sufyan with the same chain of transmitters, but he made no mention of the act of 'A'isha (being admitted as a wife in the house of the Holy Prophet).
