Allah tells us how the disbelievers mocked the Messenger when they saw him. This is like the Ayah,

﴿ظˆظژط¥ظگط°ظژط§ ط±ظژط¢ظƒظژ ط§ظ„ظ‘ظژط°ظگظٹظ†ظژ ظƒظژظپظژط±ظڈظˆط§ظ’ ط¥ظگظ† ظٹظژطھظ‘ظژط®ظگط°ظڈظˆظ†ظژظƒظژ ط¥ظگظ„ط§ظ‘ظژ ظ‡ظڈط²ظڈظˆط§ظ‹﴾

(And when the disbelievers see you, they take you not except for mockery) (21:36), which means that they tried to find faults and shortcomings in him. Here Allah says:

﴿ظˆظژط¥ظگط°ظژط§ ط±ظژط£ظژظˆظ’ظƒظژ ط¥ظگظ† ظٹظژطھظ‘ظژط®ظگط°ظڈظˆظ†ظژظƒظژ ط¥ظگظ„ط§ظ‘ظژ ظ‡ظڈط²ظڈظˆط§ظ‹ ط£ظژظ‡ظژظ€ط°ظژط§ ط§ظ„ظ‘ظژط°ظگظ‰ ط¨ظژط¹ظژط«ظژ ط§ظ„ظ„ظ‘ظژظ‡ظڈ ط±ظژط³ظڈظˆظ„ط§ظ‹ ﴾

(And when they see you, they treat you only in mockery (saying): "Is this the one whom Allah has sent as a Messenger'') i.e., they said this by way of belittling and trying to undermine him, so Allah put them in their place, and said:

﴿ظˆظژظ„ظژظ‚ظژط¯ظگ ط§ط³ظ’طھظڈظ‡ظ’ط²ظگظ‰ط،ظژ ط¨ظگط±ظڈط³ظڈظ„ظچ ظ…ظ‘ظگظ† ظ‚ظژط¨ظ’ظ„ظگظƒظژ﴾

(And indeed Messengers before you were mocked at) (6:10)

﴿ط¥ظگظ† ظƒظژط§ط¯ظژ ظ„ظژظٹظڈط¶ظگظ„ظ‘ظڈظ†ظژط§ ط¹ظژظ†ظ’ ط،ظژط§ظ„ظگظ‡ظژطھظگظ†ظژط§﴾

(He would have nearly misled us from our gods,) They meant: `he nearly turned us away from worshipping idols, and he would have done so, had we not been patient and persevered in our ways.' So Allah said, warning and threatening them:

﴿ظˆظژط³ظژظˆظ’ظپظژ ظٹظژط¹ظ’ظ„ظژظ…ظڈظˆظ†ظژ ط­ظگظٹظ†ظژ ظٹظژط±ظژظˆظ’ظ†ظژ ط§ظ„ظ’ط¹ظژط°ظژط§ط¨ظژ﴾

(And they will know, when they see the torment...)
