With regard to rulings and his understanding of life and circumstances and his evaluation of the experiences he goes through, the Muslim bases all of that on the reasoning, wisdom, and measures that Allah, may He be glorified and exalted, has enjoined us to pay attention to and follow. This is what Islam teaches us; it instructs us to examine, contemplate and weigh up reason and experience, then to make our decisions after that regarding people and actions.
Allah, may He be glorified and exalted, says (interpretation of the meaning):
“Thus Allah makes clear His Ayat (Laws) to you, in order that you may understand”
In the religion of Islam, there is nothing that suggests that a person should rely on dreams and visions, both with regard to worldly matters and religious affairs. The knowledge from dreams is subjective and is not reliable. There is no certainty with regard to it. In fact it is the matter of doubt and it is not possible that Islam would instruct people to refer for knowledge to sources that are imaginary and cannot meet the least academic standards.
It was narrated from Abu Hurayrah (may Allah be pleased with him) that the Prophet (blessings and peace of Allah be upon him) said: Dreams are of three types: a good dream which is glad tidings from Allah, a dream from the Shaytaan which causes distress, and a dream that comes from what a man is thinking of to himself…”
Narrated by Muslim (2263).
Based on this hadith we can infer that the shaytaan plays a role in what people see in their dreams and not all dreams are worth considering. Most of them can be misleading. A Muslim is not in a position to base his decision on something so uncertain and when he knows that the Shaytaan may have played the greatest role in producing it?
That also applies to the case of marriage. The Prophet (blessings and peace of Allah be upon him) has set out for us the characteristics on which we should base our decision of accepting or rejecting a suitor, as he said:
“If there comes to you one with whose character and religious commitment you are pleased, then marry (your female relative under your guardianship) to him, for if you do not do so, there will be tribulation and great mischief on earth.” They said: O Messenger of Allah, even if there are some reservations concerning him?? He said: “If there comes to you one with whose character and religious commitment you are pleased, then marry (your female relative under your guardianship) to him,” three times Narrated by al-Tirmidhi (1085); he said: It is hasan ghareeb. Classed as hasan by al-Albaani inSaheeh al-Tirmidhi.
Hence the character of a person and his religious commitment is considered to base a decision of marriage with him and not some dream. The acceptance and rejection of a suitor must not be done on account if dreams rather on the characteristics described by Prophet Muhammad(peace be upon him).
One should not pay attention to anything else or respond to whatever she sees in her dreams of things in which the Shaytaan may have played a part, seeking to divide spouses and cause division and conflict.
Shaykh Ibn 'Uthaymeen (may Allah have mercy on him) was asked the following question in Liqa' al-Baab al-Maftooh (no. 5/question no. 17):
A man proposed marriage to a woman, and in a dream, she saw him clean-shaven. Should she agree to marry him or not? In real life he appears to be good, and he does not shave his beard; he is religiously-committed, but Allah knows best about him.
He (may Allah have mercy on him) replied:
If a woman sees a man who has proposed to her as clean-shaven in a dream, when in reality he does not shave his beard, what she sees in her dream does not matter, and that should not prevent her from marrying him, so long as he is upright in his religious commitment and character. End quote.
And Allah knows best.
