I am new in Islam and I was wondering where or not that as Muslim am I allowed to believe in lucky? Is there good luck or bad luck in Islam or is it Allah?
The concept of "luck" or "coincidence” is not recognised in Islam as everything is said to be destined by Allah Subhana wa Ta’ala. We are supposed to believe that we have a destiny that has been laid out for us and all the decisions we make and experiences we go through will finally lead us there.
Salaam Alaiykum, Alhamdilollah, welcome to Islam! All things in the universe are destined by Allah wa Ta’ala Who knows the Unseen and what will happen prior to its occurrence. He also knows all that has happened from the very beginning of time as we know it and time which we cannot comprehend.
A Muslim believes that his/her time of death, sustenance and means of livelihood were pre-determined by Allah wa Ta’ala while the human was still a foetus in the mother’s womb. In this regard, the Prophet (peace and blessings be upon him) is reported to have said,
"Verily the creation of each one of you is brought together in his mother's belly for forty days in the form of a seed, then he is a clot of blood for a like period, then a morsel of flesh for a like period, then there is sent to him the angel who blows the breath of life into him and who is commanded about four matters: to write down his means of livelihood, his life span, his actions, and whether he is happy or unhappy.”
Also, Almighty Allah tells us in the Qur’an that one’s sustenance is pre-determined in heaven when He says: “And in the heaven is your providence and that which ye are promised.” (Adh-Dhariyat: 22)
It is also important not to forget that in life, as humans, we have the free will to take life into the direction in which we want it to go, and this is what we are judged against. Allah without a doubt has the knowledge of the unseen, our choices and therefore has written the destiny.
With our free will that Allah Subhana wa Ta’ala has given us to act and choose, we do create situations which can be termed as fortunate or unfortunate for ourselves. This explains ‘being in the right place at the right time’ or ‘being in the wrong place at the wrong time’, for example: boarding a plane which will crash, meeting a knowledgeable person who will teach us important aspects of our deen etc.
Our destiny intertwines utilising of our free will and Allah’s pre-written destiny.
Thus, in the life of the Muslim there is no room for luck or coincidence. Rather, he is to act according to the commands of Allah and His Prophet (peace and blessings be upon him) and to firmly believe that this is a form of taking the necessary worldly measures and that the results are up to Allah.
Some things only appear to be by luck or coincidence because of our limited knowledge and in some cases, ignorance. InshaÁllah, this information will help you to clarify your question. Salaam
