Answer
(Fatwa: 304/306=L)
It is wajib for men to grow beard, keeping beard to one fist is sunnah-e-muakkadah while trimming it below one fist is makrooh-e-tahreemi; therefore shaving beard or trimming it below one fist for job and other reasons is unlawful. As far as the matter of rizq (livelihood) is concerned one should rely only on Allah, he is alone the Provider of Livelihood, one should spend ones life according to His commandments and the beautiful way of the Prophet (صلی اللہ علیہ وسلم).
Allah says: وکأین من دابۃ لا تحمل رزقھا اللہ یرزقھا و ایاکم (الآیۃ)
“How many are the creatures that carry not their own sustenance? It is Allah who feeds (Both) them and you: for He hears and knows (All things).” (29/60)
Also, He says: ومن یتق اللہ یجعل لہ مخرجاً الخ
Whosoever fears All?h and keeps his duty to him, He will make a Way for Him to get out (from Every difficulty). And He will provide Him from (sources) He never could imagine. And whosoever puts his trust In All?h, Then He will suffice Him.
Allah (Subhana Wa Ta’ala) knows Best
