assalaamualaikum,
can anyone plz share the arabic text for this hadeeth if possible?
also, I've previously heard that its necc to recite this durood "before speaking to anyone" also.. is this correct? what if parents are calling..or theres a need to answer the house door/phone etc?

I don't know if reward is lost if you talk to someone, but if your parent calls you then its fardh upon you to stop what you're doing and obey them. Listening to parents is a fardh, while this deed is a sunnah.
And if you need to answer the door or phone its ok, you can continue on from where you left off. Allah will not waste you're a'mal for such a small reason, He is al-Kareem, you'll get the full reward.
