After looking further into the Medicare Plans C & D, we have found that there are many different types of plans offered by many different private companies who are outsourced by the government which offers the original Medicare. These companies offer these secondary plans known as Medicare Advantage Plans for an additional cost or premium which is over and above Plan A, which is often referred to as the premium-free plan.
The following website mentions the fact that there are premiums and monthly costs for such plans: https://www.medicare.gov/your-medicare-costs/medicare-costs-at-a-glance
Once a premium or fee is charged for this co-insurance, it will follow the same ruling as other insurances, which are impermissible. Hence, it will not be permissible to earn a commission by encouraging and aiding others to sign up for such plans. This act is a form of assisting in sin and Allah Ta’ala has guided the believers in the Holy Quran by mentioning,
وَتَعَاوَنُوا عَلَى الْبِرِّ وَالتَّقْوَىٰ ۖ وَلَا تَعَاوَنُوا عَلَى الْإِثْمِ وَالْعُدْوَانِ ۚ وَاتَّقُوا اللَّهَ ۖ إِنَّ اللَّهَ شَدِيدُ الْعِقَابِ
“And help and assist one another in righteousness and piety and don’t assist one another in sin and transgression. Fear Allah; verily Allah is severe in punishment.” (Surah Al-Ma’idah : 02)
As for the usage of a non-Islamic name, it is of a secondary nature in this case. Once it has been established that this type of work is not permissible due to its intrinsic nature, it will be redundant to delve into this issue.
Nonetheless, it is not permissible to try to deceive people in business or in sales by changing one’s name, if that indeed is the underlying intent for not using one’s real name. Similarly, it is not permissible to change one’s name to a non-Islamic name if the intent is to follow the ways of the non-Muslims due to some infatuation with the non-Muslims or due to an inferiority complex as this act further diminishes a person’s faith in the religion of Islam.
However, assuming a person works to earn commission through sales of a halal product; it would be permissible for a person to adopt a secondary non-Muslim “stage name” out of necessity for doing business with people who might be averse to doing business with Muslims, or people of other cultures. Again, this is not advised unless one truly feels that many otherwise halal sales will be lost merely for using one’s real Muslim name. One suggestion is to adopt a stage name that has both Islamic and non-Muslim usage such as Adam. Since we are all descendants of Adam (alayhi salaam), it would sort of suffice as a kind of surname as well, albeit a very far distant surname.
Note: The answer is in accordance to the Hanafi Madhab.
