The strongest signs:
Out of His supreme kindness towards His servants, He warns, encourages, intimidates, promises, and threatens them, as He wants to lead them to what is good and beneficial for them.
{...And Allah warns you of Himself, and Allah is All-Kind to [His] servants.}
[Surat Āl ‘Imrān: 30]
One of the signs of His kindness is that He revealed the Book to His Messenger so as to bring people out of darkness into light by His permission. Allah Almighty says:
{It is He Who sends down upon His Servant verses of clear evidence that He may bring you out from darknesses into the light. And indeed, Allah is All-Kind and Most Merciful to you.}
[Surat al-Hadīd: 9]
Another sign of His kindness is that He subjected to us means of transportation, such as horses, mules, and donkeys in the past, and cars, planes, trains, etc. in modern times. Allah Almighty says:
{And they carry your loads to a land you could not have reached except with difficulty to yourselves. Indeed, your Lord is All-Kind, Most Merciful.}
[Surat an-Nahl: 7]
Signs of His kindness also include the fact that whatever He buys from His servants -like their lives and wealth -does originally belong to Him, and He gives them abundant rewards in return. He says:
{And of the people is he who sells himself, seeking means to the approval of Allah. And Allah is All-Kind to [His] servants.}
[Surat al-Baqarah: 207]
And as part of His supreme kindness, He answers the supplications of His close servants. Allah Almighty says:
{And [there is a share for] those who came after them, saying: “Our Lord, forgive us and our brothers who preceded us in faith and put not in our hearts [any] resentment toward those who have believed. Our Lord, indeed You are All-Kind and Most Merciful.”}
[Surat al -Hashr: 10]
Another aspect of His kindness is that He laid down certain punishmentsthat deter people from committing crimes and drive them to adhere to piety. Indeed, it is out of kindness to reform those to whom kindness is to be shown. Kindness is a higher and more gentle form of mercy.
Allah Almighty says:
{And if it had not been for the favor of Allah upon you and His mercy... and because Allah is All-Kind, Most Merciful.}
[Surat an-Nūr: 20]
Another sign of His kindness is that He gives respite to the disbelievers and sinners instead of seizing them unexpectedly while they are not aware. And He also gives them safety, good health, and sustenance. Allah Almighty says:
{Or that He would not seize them gradually [in a state of dread]? But indeed, your Lord is All-Kind and Most Merciful.}
[Surat an-Nahl: 47]
And one of the signs of His kindness is that He holds
{...the sky from falling upon the earth, unless by His permission. Indeed Allah is All-Kind and Most Merciful to people.}
[Surat al-Hajj: 65]
