Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu alayhi wa sallam) said,
“The best month for observing Saum (fasting) next after Ramadan is the month of Allah, the Muharram; and the best Salat (prayer) next after the prescribed Salat is Salat at night (Tahajjud prayers).”

Abu Sa’eed al Khudri (Allah be pleased with him) reported Allah’s Messenger (صلى الله عليه و سلم) as saying:
Every servant of Allah who observes fast for a day in the way of Allah, Allah would remove, because of this day, his face farther from the Fire (of Hell) to the extent of seventy years’ distance.
From Ameer-ul-Mu’mineen Abu Hafs Umar bin Al-Khattab, who said: I heard the Messenger of Allaah -sallAllaahu alayhi wa sallam- say:
” إنَّمَا الْأَعْمَالُ بِالنِّيَّاتِ، وَإِنَّمَا لِكُلِّ امْرِئٍ مَا نَوَى”.
‘Indeed actions are but by intentions and every man shall have that which he intended.’
[Collected by Bukhari and Muslim]
Having a great regard for intentions was the transactions of the hearts of the Companions –Radhi Allaahu anhum– and those who about Allaah and the scholars who raise the people. Indeed they would perform one action and they would have many intentions for that action, so that they could gain great rewards for themselves with every intention.

Abu Umaamah (radiya Allaahu ‘anh) related that the Prophet (sall Allaahu ‘alayhi wa sallam) said :
“Each of [the following] three has a guarantee with Allâh – that if he lives, he is taken care of , and if he dies, he will enter Paradise: One who enters his house with ‘Salaam’ has a guarantee with Allâh ‘Azza Wa-Jall (The Most Mighty and Exalted); One who goes out to the Masjid has a guarantee with Allâh; and One who geos out in the way of Allâh has a guarantee with Allâh.”
