Imam Kazim(as) is reported to have said "Rajab is (the name of) a River in paradise that is whiter than milk & sweeter than honey. Allah will allow one to drink from this river if he fasts for even one day in this month.It is also a month of seeking forgiveness more than usual as Allah is forgiving & merciful during this month.
[The Greatness of the Month of Rajab Translated by Saleem Bhimji from the book Al-Muraqabat written by Ayatullah Hajj Mirza Jawad Malik Tabrizi (may Allah sanctify his soul)]
This month is one of the noblest of months for the following reasons:
1. It is one of the Sacred Months (there are four of these in the Islamic calendar).
2. It is one of the months of Supplication and even during the period of Ignorance (before the coming of Islam) this was well known amongst the people and the Arabs of that time would always wait and anticipate the coming of this month so that they could supplicate and ask their needs.
3. This month is the month of Amir Al-Mo’minin `Ali ibn Abi Talib (peace be upon him) just as it has been mentioned in the ahadith and as we are also told that the month of Sha`ban is the month of the Messenger of Allah (prayers be upon him and his family) and the Month of Ramadhan is the month of Allah (Glory and Greatness be to Him).
4. The first night of this month is one of the four nights in the year which it has been emphasized that we should stay awake in prayer and worship.
5. In relation to the 15th of this month, it has been mentioned that it is the most loved of days in the sight of Allah (Glory and Greatness be to Him) and it is the time when we should perform the action known as “Istiftah” which shall be explained in detail later on in this discussion.
6. The 27th of this month is the date when the official appointment of the Noble Prophet (prayers be upon him and his family) took place and it is the day when the mercy and blessings of Allah (Glory and Greatness be to Him) were physically manifested upon this Earth – something which this world has never seen from its inception until today.
This is a glimpse at some of the benefits of this month, as we do not possess the ability and capacity to fully understand and appreciate all of the greatness that is accompanied with this month.
One of the important things which must be observed in this month is to keep in mind the hadith “Malak Da’ee” which has been narrated from the Noble Prophet (prayers be upon him and his family).
The Noble Messenger of Allah (prayers be upon him and his family) has related that, “Allah the Most High has placed an Angel in the seventh heaven who is referred to as ‘Da’ee’. When the Month of Rajab approaches, this Angel repeats the following prayer every night until the morning time, ‘Congratulations to those who are busy in the glorification of Allah. Congratulations to those who are obeying the commands of Allah.’ Allah (Glory and Greatness be to Him) then replies, ‘I sit in the company of that person who sits in My Company, and I obey the commands of that person who obeys My Commands and I forgive that person who also forgives others. The month is my month and the servant is my servant and the mercy (shown) is my mercy. Whoever calls me during this month, I will surely reply to him and whoever requests something from Me, I will surely grant that to him and whosoever requests guidance from Me, I will truly guide him. I have made this month as a link between myself and my servants and whoever takes hold of this link will surely reach me.”
It is shame when we reflect on our level of obedience to Allah!
Where are the people who would sincerely thank Allah (Glory and Greatness be to Him)?
Where are the people who are sincerely striving to reach Allah (Glory and Greatness be to Him)? Do those people who possess intelligence have the ability to understand the truth that is contained within this heavenly call? Why then is there no answer given to this call?
Where are those with a deep spiritual insight into Allah (Glory and Greatness be to Him) – those people who know that not a single other person amongst all of the creation has the ability to truly thank Allah (Glory and Greatness be to Him) for his blessings as they are able to?
Where are those people who have lapses and slips on their record that they would be able to answer this heavenly call and proclaim, ‘I have answered the call and am ready to assist you? Greetings upon you O’ beautiful caller towards Allah; O’ King of Kings; the Most Merciful of those who can show mercy; O’ Allah – the Most Patient and Generous; the Friend of those who feel contempt for their own souls; The One who possesses Great forgiveness; the one who will change our bad deeds into righteous actions!’
