What is the procedure of doing bequest in Islam?

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ شَهَٰدَةُ بَيۡنِكُمۡ إِذَا حَضَرَ أَحَدَكُمُ ٱلۡمَوۡتُ حِينَ ٱلۡوَصِيَّةِ ٱثۡنَانِ ذَوَا عَدۡلٖ مِّنكُمۡ أَوۡ ءَاخَرَانِ مِنۡ غَيۡرِكُمۡ إِنۡ أَنتُمۡ ضَرَبۡتُمۡ فِي ٱلۡأَرۡضِ فَأَصَٰبَتۡكُم مُّصِيبَةُ ٱلۡمَوۡتِۚ تَحۡبِسُونَهُمَا مِنۢ بَعۡدِ ٱلصَّلَوٰةِ فَيُقۡسِمَانِ بِٱللَّهِ إِنِ ٱرۡتَبۡتُمۡ لَا نَشۡتَرِي بِهِۦ ثَمَنٗا وَلَوۡ كَانَ ذَا قُرۡبَىٰ وَلَا نَكۡتُمُ شَهَٰدَةَ ٱللَّهِ إِنَّآ إِذٗا لَّمِنَ ٱلۡأٓثِمِينَ ١٠٦

Believers! When death approaches you, let two men of equity among you act as witnesses when you make your bequest; or let two of those from others than yourselves act as witnesses if you are on a journey when the affliction of death befalls you. Then if any doubt occurs you shall detain both of them (in the mosque) after the Prayer, and they shall swear by Allah: 'We shall neither sell our testimony in return for any gain even though it concerns any near of kin nor shall we conceal our testimony which we owe to Allah, for then we should become among sinners.' .

Aey logon jo iman laye ho, jab tum mein se kisi ki maut ka waqt aa jaye aur woh wasiyat kar raha ho to uske liye shahadat ka nisab yeh hai ke tumhari jamaat mein se do (two) sahib-e-adal aadmi gawah banaye jayein, ya agar tum safar ki halat mein ho aur wahan maut ki museebat pesh aa jaye to gair muslimon hi mein se do gawah le liye jaye. Phir agar koi shakk padh jaye to namaz ke baad dono gawahon ko (masjid mein) roak liya jaye aur woh khuda ki kasam kha kar kahein ke “hum kisi zaati faiyde ke evaz shahadat bechne waley nahin hain, aur khwa koi hamara rishtedaar hi kyun na ho ( hum uski riayat karne waley nahin) aur na khuda waste ki gawahi ko hum chupane waley hain, agar humne aisa kiya to gunaah-gaaron mein shumar hongey”

فَإِنۡ عُثِرَ عَلَىٰٓ أَنَّهُمَا ٱسۡتَحَقَّآ إِثۡمٗا فَـَٔاخَرَانِ يَقُومَانِ مَقَامَهُمَا مِنَ ٱلَّذِينَ ٱسۡتَحَقَّ عَلَيۡهِمُ ٱلۡأَوۡلَيَٰنِ فَيُقۡسِمَانِ بِٱللَّهِ لَشَهَٰدَتُنَآ أَحَقُّ مِن شَهَٰدَتِهِمَا وَمَا ٱعۡتَدَيۡنَآ إِنَّآ إِذٗا لَّمِنَ ٱلظَّٰلِمِينَ ١٠٧

Then if it is discovered later that the two are guilty of such sin, then two others shall stand in their place from among those against whom the two had sinfully deposed, and swear by Allah: 'Our testimony is truer than the testimony of the other two, and we have not transgressed in our statement; for then indeed we would become wrong-doers.'

Lekin agar pata chal jaye ke in dono ne apne aap ko gunaah mein mubtila kiya hai to phir inki jagah do aur shaks jo inki ba-nisbat shahadat dene ke liye ehal-tar hon un logon mein se khade hon jinki haqq talfi hui ho, aur who khuda ki qasam kha kar kahen ke “hamari shahadat unki shahadat se zyada bar-haqq hai aur humne apni gawahi mein koi zyadati nahin ki hai, agar hum aisa karein to zalimon mein se hongey”

ذَٰلِكَ أَدۡنَىٰٓ أَن يَأۡتُواْ بِٱلشَّهَٰدَةِ عَلَىٰ وَجۡهِهَآ أَوۡ يَخَافُوٓاْ أَن تُرَدَّ أَيۡمَٰنُۢ بَعۡدَ أَيۡمَٰنِهِمۡۗ وَٱتَّقُواْ ٱللَّهَ وَٱسۡمَعُواْۗ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلۡفَٰسِقِينَ ١٠٨

Thus it is more likely that they will either bear the right testimony or else they will at least fear that their oaths may be rebutted by other oaths. Have fear of Allah and pay heed. Allah does not direct the disobedient to the right way.

Is tareeqe se zyada tawaqqu ki ja sakti hai ke log theek theek shahadat denge, ya kam az kam is baat hi ka khauff karenge ke unki kasamon ke baad dusri kasamon se kahin unki tardeed na ho jaye. Allah se daro aur suno, Allah nafarmani karne walon ko apni rehnumayi se mehroom kar deta nahin hai
