In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Imam Muhammad Ibn Salih Al-Uthaymeen, may Allah have mercy upon him, said:

The Sunnah has shown that one should give concern to the main objective in every affair, and this can be found in the hadith of It’ban ibn Malik, may Allah be pleased with him. It’ban requested the Prophet, peace and blessings of Allah be upon him, to come to his house and perform prayer in the place he chose as a Musallah. [1] The Prophet promised to fulfil his request, so he prepared some food for him and informed his neighbours about it. When the Prophet arrived, It’ban informed him about what he did, but the Prophet said, “Where do you want me to pray in your house?” It’ban showed him the place and he prayed before eating the food and sitting with the people. This is because he came for a specific objective. Therefore, do not be diverted – by those things you did not desire initially- from the objective you desired because that would waste your time. This is a, matter related to Uluww Al-Himmah [i.e. having a high aspiration].

The complete hadith regarding this incident

[1] Narrated It’ban Bin Malik, may Allah be pleased with him, who was one of the companions of Allah’s Messenger, peace and blessings of Allah be upon him, and one of the Ansaar who took part in the battle of Badr: I came to Allah’s Messenger and said, “O Allah’s Messenger, I have weak eyesight and I lead my people in prayers. When it rains the water flows in the valley between me and my people so I cannot go to their mosque to lead them in prayer. O Allah’s Messenger! I wish you would come to my house and offer Salaah in it so that I could take that place as a Musalla [appointed place for Salaah].” Allah’s Messenger said, “If Allah will, I will do so”. Next day after the sun rose high, Allah’s Messenger and Abu Bakr came, and Allah’s Messenger asked for permission to enter. I gave him permission and he did not sit on entering the house but said to me, “Where do you like me offer Salaah?” I pointed to a place in my house. So Allah’s Messenger stood there and said, ‘Allahu Akbar’, and we all got up and aligned behind him and offered a two-Rak’at prayer and ended it with Tasleem. We requested him to stay for a meal called “Khazira” which we had prepared for him…. [Al-Bukhari 425]
