The word(s) "swear" appears 60 time(s) in 57 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) They swear by Allah that they did not speak, and certainly they did speak, the word of unbelief, and disbelieved after their Islam, and they had determined upon what they have not been able to effect, and they did not find fault except because Allah and His Apostle enriched them out of His grace; therefore if they repent, it will be good for them; and if they turn back, Allah will chastise them with a painful chastisement in this world and the hereafter, and they shall not have in the land any guardian or a helper.

(12) They will swear to you by Allah when you return to them so that you may turn aside from them; so do turn aside from them; surely they are unclean and their abode is hell; a recompense for what they earned.

(13) They will swear to you that you may be pleased with them; but if you are pleased with them, yet surely Allah is not pleased with the transgressing people.

(14) And those who built a masjid to cause harm and for unbelief and to cause disunion among the believers and an ambush to him who made war against Allah and His Apostle before; and they will certainly swear: We did not desire aught but good; and Allah bears witness that they are most surely liars.

(15) And warn people of the day when the chastisement shall come to them, then those who were unjust will say: O our Lord! respite us to a near term, (so) we shall respond to Thy call and follow the apostles. What! did you not swear before (that) there will be no passing away for you!

(16) And they swear by Allah with the most energetic of their oaths: Allah will not raise up him who dies. Yea! it is a promise binding on Him, quite true, but most people do not know;

(17) And let not those of you who possess grace and abundance swear against giving to the near of kin and the poor and those who have fled in Allah's way, and they should pardon and turn away. Do you not love that Allah should forgive you? And Allah is Forgiving, Merciful.

(18) And they swear by Allah with the most energetic of their oaths that if you command them they would certainly go forth. Say: swear not; reasonable obedience (is desired); surely Allah is aware of what you do.

(19) They said: swear to each other by Allah that we will certainly make a sudden attack on him and his family by night, then we will say to his heir: We did not witness the destruction of his family, and we are most surely truthful.

(20) And at the time when the hour shall come, the guilty shall swear (that) they did not tarry but an hour; thus are they ever turned away.
