Question 325: 1) Does it rain in heaven? 2) May we can rest in heaven?

Answer 325: A 1: According to the Holy Quran, the answer to your question is yes. There you will have all that you desire such as rain, snow and etc. and there are other blissful things with Allah, the Almighty which we have no knowledge of. This means that Allah (SW) will grant us anything even more than we deserve. In the Holy Quran Allah (SWT) says: “There they will have whatever they wish, and with Us there is yet more.”

The Arabic version of this verse is as follows:
لَهُمْ ما يَشاؤُنَ فيها وَ لَدَيْنا مَزيد
Also, there is another verse of the holy Quran in which Allah (SWT) says: “And you shall have therein what your souls desire and you shall have therein what you ask for”.
The Arabic version:
وَ لَكُمْ فيها ما تَشْتَهي‏ أَنْفُسُكُمْ وَ لَكُمْ فيها ما تَدَّعُون‏

A 2: If you want to stop being active for a period of time in order to relax and get back your strength, you need to rest. But, you won’t feel tiered or lose your strength to get it back by resting in the Heaven.
In the Holy Quran Allah (SWT) says in this regards: “Abiding therein; they shall not desire removal from them”. So, we won’t get bored in the Heaven, but in the World. Because, Life of the world is only a (passing) enjoyment, and surely the hereafter is the abode to settle.
If we ourselves want to rest in the Heaven we would be able to, but it doesn’t mean that we get bored or lose our strength in order to get it back by.
