You've "searched and searched" but not done a simple Google search on Hamas Leaders Luxury. The question really is why are you trying to defend Hamas by denying what is easily found on the internet?
I just Googled it and found a raft of articles, including:
New York Post Hamas leaders worth staggering $11B revel in luxury — while Gaza’s people suffer
While their people languish in poverty and are treated as human shields, the leaders of Hamas live billionaire lifestyles.
The terror group’s three top leaders alone are worth a staggering total of $11 billion and enjoy a life of luxury in the sanctuary of the emirate of Qatar.
Daily Mail How Hamas's corrupt billionaire leaders cruelly lined their own pockets with cash meant for poverty-stricken Gazans - and you might have paid for it...
The image is striking in its incongruity. In the concrete and gloom, amid the detritus of terror and war, the wife of former Hamas leader Yahya Sinwar makes her way through a tunnel – deep beneath the streets of Gaza – clutching what looks like a Hermes Birkin bag worth £26,000.
Sinwar himself was 'martyred', to use Hamas's term, in Rafah in the Gaza Strip last Wednesday. But others of the terror group's commanders prefer to loll in luxury in the Gulf state of Qatar.
Three of them – Ismail Haniyeh, who was assassinated by the Israelis in Tehran on July 31, Moussa Abu Marzouk and Khaled Meshaal – were worth a reported £8.8 billion combined. Meshaal, who may well be the next Hamas leader, is worth an estimated £3.2 billion alone, according to the Israelis. You could feed and house the whole of Gaza for that.
The three commanders are said to have lived for the most part at the Four Seasons hotel in Doha, with its two pools, private beach and the 5,300 sq ft Royal Suite that comes with three balconies and a grand piano.
