Hadith no 1:

Narrated 'Umar bin Al-Khattab: I heard Allah's Apostle saying, "The reward of deeds depends upon the intentions and every person will get the reward according to what he has intended. So whoever emigrated for worldly benefits or for a woman to marry, his emigration was for what he emigrated for."

Commentary by Ibtisam Elahi Zaheer :

The first hadith of Bukharee narrated by Umer bin khattab radi Allahu anhu clearly indicates that acts are identified by their intentions.Any act which is done with pure intention to please Allah swt will be accepted by Allah swt and any act which is not done with pure intention will either be rejected by Allah swt or will acquire less reward depending on the quality of intention of the doer.

According to authentic hadith of Rasool salal laho aliehi wasalam on the day of judgement a scholar,a fighter in the way of Allah swt and a person who was spending his money on people will be thrown in hell fire .It will be due to the reason that they had done all these acts for fame and thereforeAllah swt will reject all these good deeds.

Similarly prophet salal laho aliehi wasalam gave example of horse.He told horses are of three types .One is horse that is deputed in the way of Allah swt other which is kept to fulfil day to day needs and third one is the horse which is kept to express social status and pride .When the owner of the first type of horse feeds the horse and when that horse takes a single step ahead and even when it urinates the owner gets reward but when the owner of the third type of horse feeds the horse and when that horse takes a single step ahead and even when it urinates the owner earns wrath against it.

The example of emigration is very thought provoking because it is indeed an act of great reward .Allah swt has said in the Holy Quran :

He who emigrates (from his home) in the Cause of Allâh, will find on earth many dwelling places and plenty to live by. And whosoever leaves his home as an emigrant unto Allâh and His Messenger, and death overtakes him, his reward is then surely incumbent upon Allâh. And Allâh is Ever Oft¬Forgiving, Most Merciful. (An-Nisa 4:100)

But hadith clearly indicates that Allah swt will give the reward to emigrant according to his intention .Any one who is travelling to protect his Iman,to seek knowledge of deen and to please Allah swt will be different from the traveller who is travelling for business and marriage. Travelling for business and marriage is allowed but travelling purely for sake of Allah swt is an act of worshipping So Allah swt will deal every person according to his intention. A man can hide his intention from other human beings but Allah swt is well aware of the intentions of His creation.
