Swearing by other then Allah SWT
Ruling on swearing by the Prophet peace and blessings of Allaah be upon him)
Praise be to Allaah.
This swearing by the Prophet (peace and blessings of Allaah be upon him) is haraam, and is a kind of Shirk, because swearing by something implies veneration of it, and a created being cannot venerate another created being. Hence the Prophet (peace and blessings of Allaah be upon him) said: “Whoever swears by anything other than Allaah is guilty of kufr or shirk.” (Saheeh, narrated by Ahmad, 2/125; Abu Dawood, 3251; al-Tirmidhi, 1535).
This applies to swearing by the Prophets, angels, righteous people and all other created beings. And the Prophet (peace and blessings of Allaah be upon him) said: “Whoever swears an oath, let him swear by Allaah or else remain silent.” (Narrated by al-Bukhaari,4860 – al-Fath 8/611 and 6107 – al-Fath 10/516; Muslim, 1647; Ahmad, 2/309; Abu Dawood, 3247; al-Nasaa’i, 3775; al-Tirmidhi, 1545; Ibn Maajah, 2096).
With regard to the verses in the Qur’aan which contain oaths sworn by “those sent forth” (al-mursalaat), the winds that scatter (al-dhaariyaat), those who pull out (al-naazi’aat), the break of day (al-fajr), the Time (al-‘asr), the forenoon (al-duhaa) and the mansions of the stars (mawaaqi’ al-nujoom – see al-Waaqi’ah 56:75), etc., these are oaths sworn by Allaah, and Allaah has the right to swear oaths by whatever He wills, but the created being can swear only be his Lord, may he be exalted.
From al-Lu’lu’ al-Makeen min Fataawaa ibn Jibreen, p. 32
It is not permissible to swear by salaah (prayer) or by honesty
Praise be to Allaah.
It is not permissible to swear by prayer, honesty, critical situations or any other created thing. One should swear only by Allaah. One should not say “By my honesty I will do such and such”, or “by the honesty of So and so”, or “by the life of So and so” or “by my prayer”. Nor should one ask anyone else to do this and tell them, “Say ‘by my honesty/by my prayer/ by my zakaah.’” There is no basis for any of this, because prayer is the action of a person and zakaah is the action of a person, and people’s actions are not something to swear by.
One should swear only by Allaah or by His attributes, because the Prophet (peace and blessings of Allaah be upon him) said: “Whoever swears, let him swear by Allaah or keep silent.” (Saheeh, agreed upon). And he (peace and blessings of Allaah be upon him) said: “Whoever swears by anything other than Allaah has committed shirk.” (Narrated by Imaam Ahmad with a saheeh isnaad from ‘Umar (may Allaah be pleased with him)).
It was also narrated by al-Tirmidhi and Abu Dawood with a saheeh isnaad from Ibn ‘Umar (may Allaah be pleased with him) from the Prophet (peace and blessings of Allaah be upon him), with the wording, “Whoever swears by anything other than Allaah has committed kufr or shirk.” And the Prophet (peace and blessings of Allaah be upon him) said: “Whoever swears by honesty is not one of us.”
So every believing man and woman has to beware of that and not swear by anything except Allaah alone, so he should say “Wallaahi (by Allaah) I did not do such and such”, etc., if that is necessary. What is recommended in sharee’ah is to be cautious about swearing oaths, and not to swear except when essential. Allaah says (interpretation of the meaning):
“And protect your oaths (i.e. do not swear much)” [al-Maa’idah 5:89]
But if it is necessary, then one may swear by saying, “By Allaah, I did not do such and such”, provided that he is telling the truth, or, “By Allaah, I did not go to So and so” etc. If he is telling the truth, then there is nothing wrong with that, because this is swearing by Allaah when there is a need to do so.
But swearing by honesty or by the Prophet (peace and blessings of Allaah be upon him), by the Ka’bah, or by the life of So and so, or by the honour of So and so, or by my prayer, or by my honesty – this is not permissible, as stated above, because of the ahaadeeth quoted.
But if a person says “Trust me (lit. in my trust)”, this is not an oath; this means that this is something which has been entrusted to me and for which I am responsible. But if a person says “by my trust/ by my prayer/ by my father’s life”, this is not permissible, because he is swearing by something other than Allaah. We ask Allaah to guide us all.
