Is a contract considered fraudulent if the pharmacist discovers that the salaries are higher than what was agreed upon, and is it permissible for him to accept free gifts from pharmaceutical companies given to pharmacists without compromising work, and does he have the right to object to the employer preventing him from taking them, and what are the conditions for a valid contract between an employee and an employer, and is the mere continuation of the pharmacist in work considered an acceptance of the contract terms?

The conditions agreed upon in contracts, including salary determination, are binding on both parties as long as they do not violate Islamic law. The mere acceptance of the job by the worker is considered an agreement to the stipulated conditions. The agreement is not considered deception, as knowledge of wages in the country is the responsibility of the worker. Gifts given to the pharmacist by pharmaceutical companies are the right of the pharmacy owners, and the employee is not entitled to take them without the employer's permission. Any condition in an employment contract that does not contradict Islamic law and is mutually agreed upon by both parties is valid.
