Whenever my children ask me a question about Allah, the sun and earth, about cities, food, animals, babies, I note them in a diary. Do my research and explain them. I never follow a coursebook for Science, we create real projects perhaps a diorama, raise caterpillars, grow vegetables in the kitchen garden, make rainbows with mirrors. Children love project-based learning. As a Pharmacist, we have done Project-based learning in Pharmacology laboratory. I remember I injected a guinea pig with a sedative, and he never woke up! I killed him due to overdosing it. I can never forget the effects of drugs which I have practically witnessed on myself. To my surprise, we are educated enough to take ‘side-effects’ normal and not apprehensive of their long-term effects.
I remember the drug Thalidomide, it was hailed as a "wonder drug" to treat conditions such as insomnia, morning sickness and depression in pregnant women and licensed in the UK in 1958. But it was withdrawn again in late 1961 after an Australian doctor identified an increase in the number of deformed babies born in his hospital and found that all of the mothers involved had used the drug. By then around 10,000 babies had been born worldwide who either had shortened arms or legs, or no limbs at all. All controls, research-based evidence and science behind this was recorded yet no one knew was havoc it will play with human life. At times, even doctors are under so much pressure to follow the FDA regulations that they cannot practice medicine with their own understanding of drugs and human body. I look at them as conventional children, caged. What is the point of being educated if we cannot behave like one?
Allah says in the Quran, "If the sea were ink for [writing] the words of my Lord, the sea would be exhausted before the words of my Lord were exhausted, even if We brought the like of it in [continual] supplement." (Al-Kahf  : 109)
Allah says that even if those oceans were ink for the Words of Allah, and all the trees were pens, the pens would be broken and the water of the sea would run dry, and the Words of Allah would remain, for nothing can outlast them. For no one can comprehend the greatness of Allah or praise Him as He deserves to be praised, except the One Who praises Himself.
Our Lord is as He says He is and He is beyond what we can say.
The blessings of this world, the beginning and end of it, in comparison to the blessings of the Hereafter, are like a mustard seed compared to the entire world.
Ar-Rabi` bin Anas said,
"The parable of the knowledge of all of mankind, in comparison to the knowledge of Allah, is that of a drop of water in comparison to all of the oceans."
Hence, the true outcome of Project Based Learning is to understand our Lord, the Great Majesty. Humanbeings reach a higher spirituality by knowing the uloom (of Duniya or Divine uloom). In the end he discovers there is a Creator who created these Uloom, they cannot exists on their own. And if that Creator made them, He has made them for a purpose. If we find out through this learning journey what Allah uz Jal wants from us? This will be one big achievement in identifying false gods around us.
Such an education which build our bond with Allah, is the right beneficial knowledge! seeking this, is Ebadah (worship) and struggling in this path is Salvation to Allah.
