Tafseer Ibn Kathir of AL ISRAA' [68]

68. Do you then feel secure that He will not cause a side of the land to swallow you up, or that He will not send against you a Hasib Then, you shall find no guardian. Allah says, do you think that by emerging onto dry land you will be safe from His vengeance and punishment, that a side of the land will not swallow you up or He will not send against you a Hasib - which is a kind of rain that carries stones This was the view of Mujahid and others. As Allah says:

(Verily, We sent against them, except the family of Lut, them We saved in the last hour of the night, As a favor from Us.) (54:34-35) Elsewhere, Allah says:

(and We rained on them stones of Sijjil, in a well-arranged manner one after another)

(Do you feel secure that He, Who is over the heaven (Allah), will not cause the earth to sink with you, and then it should quake Or do you feel secure that He, Who is over the heaven (Allah), will not send against you a Hasib Then you shall know how (terrible) has been My warning) (67: 16-17)

(Then, you shall find no guardian.) no helper to turn the punishment away from you and save you.
