Perhaps the question I am going to ask may seem very strange, but what is making me ask it is feelings of regret and worry. What happened is: one day I wanted to fix the tires on my car with the mechanic. On my way to the repair shop, there was a puddle of water in my way, and I did not know whether it was rainwater or wastewater (sewage). I drove through it, and after I reached the repair shop, I was worried about my own safety, and I did not touch the tires of the car, because I know that wastewater and dirty things on the ground may carry dangerous bacteria or viruses that can cause diseases that are fatal to humans. But at the same time I was careless and I did not tell the mechanic to wear something protective before touching the tires, so that his hands would not be contaminated.
My question is: in the event – Allah forbid – that something bad happens to this man because of me, and he dies, would this be regarded as killing – Allah forbid – or accidental killing? What exactly would my situation be, according to sharee‘ah?
Praise be to Allah.
This anxiety that you are feeling and these worries that are making you think that you caused harm to someone else is based on nothing but doubts and waswaas (compulsive insinuating thoughts). As for the water you drove through, you do not know what its condition was at all, and the basic principle is that mud and water in the streets is pure, unless it is known that it is impure water.
Moreover, the wheels of your car drove over the ground after that, which usually helps to remove dirt and clean off whatever got stuck to the wheels before that.
But regardless of all that, such dirt is visible to the eye, so if there was anything that needed cleaning or precautions, this man would have taken care of it, because this is his profession. There would not be anything strange on your car that he would not notice; in fact he is most likely used to that, and is more knowledgeable about that which requires protection and that which does not in such cases.
Undoubtedly what you mentioned about the possibility of harm to the mechanic is no more than waswaas and whispers from the Shaytaan, which he is instilling in your mind so that you will remain anxious and worried, and upset about something that is not going to have any effect. Just as the Shaytaan seeks to tempt people and divert them from doing good by means of whims and desires, and specious arguments, he also tries to keep them from doing righteous deeds and beneficial acts by means of waswaas and sadness.
Feeling sad for something that you could not make happen or that you could not anything about if it did happen after the fact is going to cause you to suffer from waswaas and compulsive thoughts, and it will distract you from focusing on that which is in your own best interests and make you feel weak and exhausted. That is something that is not right and is blameworthy.
Hence the Prophet (blessings and peace of Allah be upon him) used to seek refuge with Allah from worry and sorrow, as is narrated in the hadeeth of Anas ibn Maalik (may Allah be pleased with him) who said: The Prophet (blessings and peace of Allah be upon him) used to say: ““Allaahumma inni a’oodhu bika min al-hammi wa’l-hazani wa’l-‘ajzi wa’l-kasali wa’l-jubni wa’l-bukhli wa dala‘ id-dayn wa ghalabat ir-rijaal (O Allaah, I seek refuge with You from worry and grief, and I seek refuge with You from incapacity and laziness, and I seek refuge with You from cowardice and miserliness, and I seek refuge with You from the stress of debt and from being overcome by men).””
Narrated by al-Bukhaari (6369).
Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) said:
With regard to “grief” or sadness, it is not enjoined by Allah or His Messenger; rather it is disallowed in some cases, even if it has to do with matters of religion, as in the verses in which Allah, may He be exalted, says (interpretation of the meaning):
“So do not become weak (against your enemy), nor be sad, and you will be superior (in victory) if you are indeed (true) believers”
[Aal ‘Imraan 3:139]
“And endure you patiently (O Muhammad), your patience is not but from Allah. And grieve not over them (polytheists and pagans, etc.), and be not distressed because of what they plot”
“and he (SAW) said to his companion (Abu Bakr ): ‘Be not sad (or afraid), surely Allah is with us.’”
“And let not their speech grieve you”
“In order that you may not be sad over matters that you fail to get, nor rejoice because of that which has been given to you”
and there are many similar verses.
That is because it does not bring any benefit or ward off any harm, so it serves no interest, and that which serves no interest cannot be enjoined by Allah… But if it leads to weakness (of faith) in the heart and distracts one from doing that which Allah and His Messenger have enjoined, then it is blameworthy.
End quote from Majmoo‘ al-Fataawa, 10/16-17
What you must do is focus on that which will benefit you and ward off from you this waswaas, compulsive thoughts, doubts and illusions.
