Narrated Ibn Abbas: The Prophet(SAW) said, “No good deeds done on other days are superior to those done on these (first ten days of Dhul Hijja).” Then some companions of the Prophet(SAW) said, “Not even Jihad?” He replied, “Not even Jihad, except that of a man who does it by putting himself and his property in danger (for Allah’s sake) and does not return with any of those things.” (Sahih Bukhari)
Narrated Aisha: Allah’s Apostle (SAW) said, “If somebody innovates something which is not in harmony with the principles of our religion, that thing is rejected.” (Sahih Bukhari)
Narrated Abu Huraira: Allah’s Apostle (SAW) said, “There are three persons whom Allah will not look at on the Day of Resurrection, nor will he purify them and theirs shall be a severe punishment. They are:
1. A man possessed superfluous water, on a way and he withheld it from travelers.
2. A man who gave a pledge of allegiance to a ruler and he gave it only for worldly benefits. If the ruler gives him something he gets satisfied, and if the ruler withholds something from him, he gets dissatisfied.
3. And man displayed his goods for sale after the ‘Asr prayer and he said, ‘By Allah, except Whom None has the right to be worshipped, I have been given so much for my goods,’ and somebody believes him (and buys them).”
The Prophet then recited: “Verily! Those who purchase a little gain at the cost of Allah’s Covenant and their oaths.” (3.77) (Sahih Bukhari)
Narrated Abu Huraira : The Prophet (SAW) said, “The saying ‘Sub Han Allah’ is for men and clapping is for women.” (If something happens in the prayer, the men can invite the attention of the Imam by saying “Sub Han Allah”. And women, by clapping their hands). (Sahih Bukhari)
Narrated Ibn ‘Umar : I accompanied Allah’s Apostle (SAW) and he never offered more than two Rakat during the journey. Abu Bakr, ‘Umar and ‘Uthman used to do the same. (Sahih Bukhari)
Narrated Ibn Abbas: The Prophet (PBUH) once stayed for nineteen days and prayed shortened prayers. So when we travel led (and stayed) for nineteen days, we used to shorten the prayer but if we travelled (and stayed) for a longer period we used to offer the full prayer. (Sahih Bukhari/Volume 2, Book 20, Number 186)
How can we feel comfortable doing anything else ignoring prayer?!
