* While, ahkam is the laws, values, stipulations or stipulations of Shari'ah (Islamic Law). Al- Ahkam is important because it beloved by the Prophet Muhammad SAW, and it receive Allah's Love and Forgiveness. Besides, it can also preserve good relationships with others.

* The difference between Adab and Ahkam is Adab is for everywhere, while ahkam is for specific adjective.

In conclusion, both of it is very important in ouf live as a sevant of Allah, but in different ways because adab can enhance our taqwa, while ahkam can enhance our iman.

This is a very common question from Muslims, people of other faiths, or no faith. There is a lot of evidence in the Qur’an and hadith that helps us answer this question of why we are tested. We should remember that Allah is Al-Adl, The Just, and He is Ar-Rahman, The Most Merciful; He never wants ill for His servants, He only wants the best for us.

1) We were created to worship Allah

We were created to worship Allah, and we all made a promise to do so before we were sent to earth. Tests are a means for us to fulfill this promise. In fact, they are a “sunnah” of Allah. Allah states in the Qur’an ( surah al-'Ankabut ayah 2-3) ‘Do the people think that they will be left to say, “We believe” and they will not be tried? But We have certainly tried those before them, and Allah will surely make evident those who are truthful, and He will surely make evident those who are false.’

2) Allah tests us to purify us and wash away our sins.

The Prophet SAW said:“No calamity befalls a Muslim but that Allah expiates some of his sins because of it, even if it were the prick of a thorn.”  [Bukhari, Muslim]. Actually, instead of seeing trials as punishment from God, this shows that God actually wants to save us from punishment. We must know that the punishment of the Hereafter which is much worse than any test faced in this Dunya.

3). Tests are given to us to strengthen our iman (faith).
The Prophet SAW said : “The people who face the most difficult tests are the prophets, then the righteous, then those following them in degree. A person is tried according to his religion. So if there is firmness in his religion, then the trial is increased, and if there is a weakness, then it is lightened. Verily a trial remains with a servant until he walks the earth having no sin left upon him.” [Bukhari]. Actually, Allah wants to refine us, out of His love and mercy, so that we can attain not just Paradise but the highest rank of the Prophets and the righteous.

4).  Allah tests a person He loves.
Why? Because if the servant reacts with Sabr and contentment with Allah’s decree, it brings them closer to Allah. And “Allah loves the Patient.” [Quran 3: 146]

In conclusion, we have to be patient in every situation, especially when Allah SWT tests us. We must remember that Allah SWT  never tests his servants except by their abilities. "Laa yukalliful-laahu nafsan illaa wus’ahaa", which means "Allah does not charge a soul except (with that within) its capacity.
