Bismillah Alhamdulillah wassalatu wasalamu ala Rasulillah wa ala Alihi wa Sahbihi.

Hadith English:

Abu Hurairah (Allah be pleased with him) reported Allah’s Messenger (may peace and blessing be upon him) as saying: The most excellent fast after Ramadan is God’s month al-Muharram, and the most excellent prayer after what is prescribed is prayer during the night (tahajjud).
[Sahih Muslim, The Book of Fasting (Kitab Al-Sawm) Rozey Ke Masayeel]
