In the book Fazail Shoor it is narrated by Hazrat Ikhtab bin Hassan (may Allah be pleased with him) that Hazrat Abu Bakr Siddique (may Allah be pleased with him) would read 12 rakats nafl on the first night of this month. There is no surah specified for these rakats. Most Companions (may Allah be pleased with them all) agree upon this.
In the same book it is narrated that in the last 10 days of Jumada Akhir (same as Jumada Al-Thani) the companions used to fast in celebration of the coming month Rajab and in the night of these 10 days they would read 20 rakats.
If on the first day of this month one reads 4 rakats and in each rakat he reads Surah Ikhlas 13 times, then 100, 000 deeds are written for him and 100, 000 deeds are erased.
