Dhu al Hijjah
Keep fast on the first 9 days (not on the 10th)
In the first ten nights, between the Maghrib and Ishaa Namaaz pray 2 Rakaat Namaaz, in every Rakaat, after Surah Hamd, recite Surah Ikhlas and the following:

[And when We did appoint for Moosa thirty nights, and added to them ten; and he completed the whole time appointed by his Lord of forty nights; and Moosa said unto his brother: “Take my place among the people. Do right, and do not follow the way of the mischief-makers”.](Sura al-A`araaf, 7:142)
