Folding one's hands after ruku when praying behind a imaam who reads longer zikr than ''Rabbana lakal hamd''

Q: Must a Hanafi fold his hands after ruku when he prays behind a imaam who does longer zikr than ''Rabbana lakal hamd'' such as;

رَبَّنا وَلَكَ الحَمْدُ حَمْداً كَثيراً طَيِّباً مُبارَكاً فيه

Rabbana wa laka l-h'amd, h'amdan kathiran tayyiban mubaarakan fih

Discharging zakaat to an organisation that builds homes for widows

Q: This is how I discharge my zakaat every year:

A certain lady is in charge of an organization that builds homes for widows, so what I do, for example, 200 000 dollars is my zakaat, so I give it to her and tell her build homes for 4 widows, sometimes I give the money directly to the bank in charge of the project, is this ok?
