Ibn Mas’ud narrated that Allah’s Messenger (ﷺ) said to his wife Umm Habiba:
Verily you have asked Allah about the duration of life already set, and the steps you would take, and the sustenance the share of which is fixed. Nothing will take place before its due time, and nothing will be deferred beyond when it is due.Sahih Muslim
Your Rizq (provisions) and your Ajal (life span) are both determined by Allah (ﷻ) and no one can change what Allah (ﷻ) has destined for you.
Allah is the Provider, the Lord of Power, the Ever Mighty.TMQ: Surah Adh-Dhariyat (51:58)
Rizq and our understanding of what it entails is not limited to money or items with a monetary value but can include things which nourish (e.g. worn or used by you), worldly blessings (e.g. children), or a great good promised by Allah (ﷻ).
Ajal on the other hand refers to a persons lifespan and the time they have been granted to live. This, like Rizq, has already been decided by Allah. The exact moment Malik Al-Mawt takes life away is fixed regardless of the circumstances under which a person may depart this dunya.
A persons life and the possessions they own are always the most dearest to them. They will go to great lengths to preserve and defend their life. Similarly, man is capable of doing anything in the pursuit of wealth. The Prophet (ﷺ) said:
Two wolves roaming freely among a flock sheep are less destructive to them than the passion of a man for wealth and fame is to his religion.Tirmidhi
Dear Ummah, the two most valuable things to you that you strive to better are already determined by Allah. No person can alter this. Neither can your lifespan be ended earlier than Allah (ﷻ) had decided, nor can the provisions Allah (ﷻ) had set aside for you be withheld from you. O Muslims, if you fail to understand this you can easily fall into sin and error. Do not disregard the Shari’ah of Allah (ﷻ) in the mistaken hope of increasing your wealth or extending your life. Do not fear the repercussions of following Allah’s commands and prohibitions, for surely that is better for you in the Hereafter.
Do not let fear of people prevent you from speaking the truth when you see it; speaking the truth and doing what is right will never advance your Ajal nor prevent Rizq.Ahmad, Ibn Habban, Ibn Majah
Therefore when Allah (ﷻ) commands the believers to do anything, they should never fear that their Rizq or Ajal will be affected. Muhammad (ﷺ) and the best of those who followed understood and demonstrated this well and Allah (ﷻ) honoured them by providing them with victory. Indeed there is no greater helper than Allah (ﷻ).
And whoever fears Allah – He will make a way out for him. And will provide for him from where he does not expect.TMQ: Surah At-Talaq (65:2-3)
