The month of Dhul-Hijjah is a season of worship, and seasons of worship bring along blessings, benefits and opportunities to correct one's faith and make up for shortcoming. Every one of these special opportunities involves some kind of worship, which brings the slave closer to his Lord. And Allâh bestows His blessings and Favours on whom He wills. The fortunate person is he who makes good use of these special months, days, and hours, while worshiping Allâh. He is most likely to be touched by the blessings of Allâh. [Ibn Rajab, al-Latâ'if pp. 8]
The first ten days of Dhul-Hijjah are marked blessed for both, the pilgrims and the non-pilgrims. Rewards of good deeds are multiplied in these days. Imâm Ibn Qayyim (rahimahullah) (d. 751H) said:
“Indeed, its days are the most excellent of all the days with Allâh. It has been confirmed in Sahîh al-Bukharî from Ibn Abbas (radhi Allâhu anhu) that the Messenger of Allâh (sallAllâhu alaihi wa-sallam) said:
“No deed are more virtuous than deeds on these days.”
The companions asked: 'Not even Jihad (fighting in Allâh's Cause)?' He (sallAllâhu alaihi wa-sallam) replied:
“Not even Jihad for the sake of Allâh, unless a man goes out risking himself and his wealth for the sake of Allâh, and does not come back with anything.”
[Sahîh al-Bukharî vol: 2, no: 457]
And it is these ten days, of which Allâh takes an oath saying:
“By the dawn; by the ten nights. [Sûrah al-Fajr (89): 1-2]
This is why it is recommended to increase in making Takbîr, Tahlil and Tamhid during these days.” [Zâd al-Ma'âd vol: 1, pp: 56]
