All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallahu ‘alayhi wa sallam, is His slave and Messenger.
It is impermissible to resort to fraud, cheating, and deceit as that mentioned in the question. The person to whom the eligibility criteria for obtaining asylum and the consequent benefits do not apply does not have the right to resort to fraud to obtain asylum. If an undeserving person resorted to lying, fraud, or bribes in order to obtain asylum, then he has combined the sins of consuming wealth unlawfully and infringement of the rights of others along with those of lying, fraud, or offering bribes. Allah, The Exalted, says (what means): {And do not consume one another's wealth unjustly or send it (in bribery) to the rulers in order that (they might aid) you (to) consume a portion of the wealth of the people in sin, while you know (it is unlawful).} [Quran 2:188]
The Prophet, sallallahu ‘alayhi wa sallam, said, “Whoever cheats, he is not one of us.” [Muslim]
‘Abdullah ibn ‘Amr, may Allah be pleased with them, said, “The Prophet, sallallahu ‘alayhi wa sallam, cursed the one who offers a bribe and the one who takes it.” [At-Tirmithi graded it hasan saheeh (good or sound)]
Those who take up such illegal actions as a profession are committing a grave sin; it is incumbent on them to refrain from such actions. They should be advised and admonished about the prohibition of their actions. If they continue to carry out these illegal actions, then they should be reported to the concerned authorities in order for them to put an end to their cheating and fraud and give the rights to the rightful beneficiaries.
Allah knows best.
