The one who looks after a widow or a poor person is like a Mujaahid (fighter) who fights for Allaah’s cause, or like him who performs prayers all the night and fasts all the day.

The Messenger of Allah (صلى الله عليه وسلم) said:
“The day of Friday has twelve hours, in which there is no Muslim slave who asks Allah for anything but He will grant it to him, so seek it in the last hour after ‘Asr.”

‘There is no Muslim who plants a plant or a tree, or sows a seed and no bird, or human or animal eats from that except that it is a charity for that person.’
[Collected by Bukhari, Muslim & Ahmad]
8 – From Jabir from the Prophet -sallAllaahu alayhi wa sallam:
‘There is no Muslim who plants a plant or a tree, except that whatever is eaten from it is a charity for him. Whatever is stolen from that is a charity for him. Whatever is eaten from it by an animal is a charity for him. Whatever a bird eats is a charity for him, no one suffers a loss except that it will be a charity for him till the Day of Judgement.’

On the authority of Abu Dharr (radiAllahu anhu), that the Prophet (sallAllahu alayhi wasallam) said –
“Whoever says ten times immediately after finishing the Fajr (Dawn) Payer, before moving from his place or talking to anyone,
“laa ilaaha illallaahu wahdahu laa shareeka lahu, lahul mulku wa lahul hamdu yuhyee wa yumeetu wa huwa alaa kulli shay’in qadeer – [ none has the right to be worshipped except Allaah alone having no partner, sovereignty is His and all praise is for Him and He brings life and He causes death and He has full power over everything,]”
ten good deeds will be recorded for him, ten sins will be eliminated from him, he will be upgraded ten degrees (in reward), he will be safeguarded from all kinds of harm all that day, he will be guarded against shaytan and no sin can overtake him on that day (and nullify his good deeds) except associating others in worship with Allaah. (At Tirmidhi no.3484 [5/515])
At-Tirmidhi commented on this hadeeth saying, “This is a hasan, saheeh hadeeth (i.e a good and authentic hadeeth)”.
Likewise it is an act of Sunnah to say dhikr ten times straight after Magrib salah too, according to a hadith related by Imaam Ahmad Hanbal (rahimahullah) on the authority of Umm Salamah (radiAllahu anha), hadith number 26430. Also stated in Sahih Ibn Hibban no. 2023.

Here is an excerpt from Ibnul Qayyim (rahimahullaah):
There is an hour of acceptance, and it is the hour in which no Muslim happens to supplicate to Allah for something except that it will be given to him. In the hadeeth reported by al-Bukharee and Muslim on the authority of Abu Hurayrah that Allaah’s Messenger (salallaahu ‘alayhi wa sallam) said:
Indeed, there is an hour (opportune time) on Friday and if a Muslim gets it while praying and asks something from Allah, then Allah will definitely meet his demand. And he (salallaahu ‘alayhi wa sallam) pointed out the shortness of that time with his hands.
Translated by brother Salah al-Iranee
Aboo Dawood (rahimahullaah) reported (no. 345) from Aws ibn Aws ath-Thaqafee (radiallaahu ‘anhu): I heard Allaah’s Messenger (salallaahu ‘alaihi wa sallam) say:
“Whoever washes his head on the day of Jumu’ah, and takes a bath and arrives in time, and he walks and he does not ride, and he draws close to the imaam, and he listens and he does not speak. Then for every step which he takes, there will be for him the reward of a year: the reward of fasting it and standing in Prayer.”
Shaikh al-Albaanee (rahimahullaah) said this hadeeth is (saheeh) authentic.

‘Arafah on Saturday 5ht November 2011 (9 Dhul-Hijjah 1432)
The ninth day of Dhul-Hijjah is the day of ’Arafah, since it is on this day that the pilgrims gather at the mountain plain of ’Arafah, praying and supplicating to their Lord.
It is mustahabb (highly recommended) for those who are not pilgrims to fast on this day, since the Prophet (sallallaahu ’alayhi wa sallam) was asked about fasting on the day of ’Arafah, so he said, “It expiates the sins of the past year and the coming year.” 
Likewise, the Prophet (sallallaahu ’alayhi wa sallam) said, ‘There is no day on which Allaah frees people from the Fire more so than on the day of ’Arafah. He comes close to those (people standing on ’Arafah), and then He reveals before His Angels saying, ‘What are these people seeking.” 
Imaam at-Tirmidhee (d.275H) – rahimahullaah – said, “The People of Knowledge consider it recommended to fast on the day of ’Arafah, except for those at ’Arafah.”
