All Praise is due to Allah, the Lord of all the worlds. Peace and blessings be on His servant and Messenger; our Prophet Muhammad, his family, and his Companions.
To commence: This is some advice I offer to remind my Muslim brothers of Allah's Rights and to call people to obey Him, as He says: And remind (by preaching the Qur'ân, O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ), for verily, the reminding profits the believers. Allah (Glorified be He) also says: Help you one another in AlBirr and AtTaqwâ (virtue, righteousness and piety); but do not help one another in sin and transgression. Allah (Glorified be He) also says: By Al'Asr (the time). Verily, man is in loss,
Except those who believe (in Islâmic Monotheism) and do righteous good deeds, and recommend one another to the truth [i.e. order one another to perform all kinds of good deeds (AlMa'ruf) which Allâh has ordained, and abstain from all kinds of sins and evil deeds (AlMunkar which Allâh has forbidden], and recommend one another to patience (for the sufferings, harms, and injuries which one may encounter in Allâh's Cause during preaching His religion of Islâmic Monotheism or Jihâd). The Prophet (peace be upon him) said: Religion is based on advising one another. Upon this we said: "For whom?" He replied: "For Allah, His Book, His Messenger and for the leaders and the general Muslims." (Related by Muslim)
The greatest thing, which I commend you and myself with, is to fear Allah (He may be Glorified) in all conditions. This is the recommendation of Allah (Exalted be He) and His Messenger (peace be upon him). Allah (Exalted be He) says: And verily, We have recommended to the people of the Scripture before you, and to you (O Muslims) that you (all) fear Allâh The Prophet (peace be upon him) said to his Companions in many Khutbah (religious sermons): I enjoin you to observe Taqwa (fearing Allah as He should be feared), and to hear and obey... The reality of Taqwa (fearing Allah as He should be feared) is to do Allah's ordinances and avoid His prohibitions. Allah (Exalted be He) commands people with piety and promises the pious to relieve their distresses, facilitate their affairs, double their rewards, and provide them with sustenance from where they do not conceive.
decision thereof is with Allâh (He is the ruling Judge). This is general in all problems, which erupt between countries and peoples. Allah (may He be Praised and Glorified) says: But no, by your Lord, they can have no Faith, until they make you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳﻠﻢ) judge in all disputes between them Allah (Glorified be He) also says: Do they then seek the judgement of (the days of) Ignorance? And who is better in judgement than Allâh for a people who have firm Faith.
So, it is obligatory on all countries, groups, tribes and Muslims to resort to Allah in arbitration regarding the issues in which they differ and to beware of aggression, injustice and to solve the problems which erupt among them through peaceful means and reasonable good mediation. In case it is not easy to do so, they must resort to Islamic arbitration not to aggression and injustice. The problem between Kuwait and Iraq must be solved through a Shar`y court composed of scholars who are known for their good knowledge, virtue and integrity to solve it according to the Book of Allah and the Sunnah of the Prophet (peace be upon him) in case peacemaking is impossible.
And whatever of misfortune befalls you, it is because of what your hands have earned. And He pardons much. (See the Qur'ân Verse 35:45).
He who repents from his sins is like the one who did not commit a sin.
By Al'Asr (the time). Verily, man is in loss, Except those who believe (in Islâmic Monotheism) and do righteous good deeds, and recommend one another to the truth [i.e. order one another to perform all kinds of good deeds (AlMa'ruf) which Allâh has ordained, and abstain from all kinds of sins and evil deeds (AlMunkar which Allâh has forbidden], and recommend one another to patience
The president of Iraq must repent to Allah, hasten to return to Him, seek His forgiveness of this manifest injustice and hasten to withdraw his army from Kuwait in order to avoid turmoil, set things back to their first positions, and reach a compromise to the problem that I mentioned. This is the opinion of all scholars without disagreement among them that all problems that erupt between countries, groups, tribes and individuals must be solved through the Shar`y means if it is impossible to solve them through the diplomatic channels, which do not go against the Shari`ah.
As for the measures which the Saudi Arabian government has taken as a result of these actions of aggression of the president of Iraq such as seeking the help of multiforces from different nationalities including Muslims and others to stop the aggression and defend the country, this is permissible. It is rather obligatory to do so and the Kingdom must play its role in defending Islam and Muslims as well as the sanctity of this country and its people.
