Prophet Hazrat Md. Sm. Never Celebration the time of His birthday

Prophet Hazrat Muhammad Sm. never make celebration the time of his birthday. But, Prophet Hazrat Muhammad Sm. celebrated his birthday time by keeping fast. He never celebrated his birthday through  using heavy food, or conference.

মহানবী (সা.) জন্ম তারিখ নয়, জন্ম বার বা জন্মের দিন উদযাপন করতেন। কিন্তু সে উদযাপনও কোনো উৎসব, মিছিল বা ভোজনরসিকতার মাধ্যমে নয়।

মহানবী (সা.) তাঁর জন্মের দিন সোমবার রোজা রাখতেন। হাদিসবিশারদরা লিখেছেন, মহানবী (সা.)-এর জন্মের কারণে প্রতি সোমবার রোজা রাখা মুস্তাহাব। হজরত আবু কাতাদাহ আনসারি (রা.) থেকে বর্ণিত, ‘মহানবী (সা.)-কে সোমবার রোজা রাখা সম্পর্কে জিজ্ঞেস করা হলে তিনি বলেন, ওই দিন আমি জন্মগ্রহণ করেছি। ওই দিনই আমি নবুয়ত লাভ করেছি বা আমার ওপর ওহি অবতীর্ণ হয়…। ’ (সহিহ মুসলিম, হাদিস : ১১৬২)

” হে আদম সন্তান, আমার ইবাদতের জন্য তুমি নিজের অবসর সময় তৈরী করো ও ইবাদাতে মন দাও, তাহলে আমি তোমার অন্তরকে প্রাচুর্য দিয়ে ভরে দিব, এবং তোমার দারিদ্র্য দূর করে দিব।

আর যদি তা না করো, তবে তোমার হাতকে ব্যস্ততায় ভরে দিব এবং তোমার অভাব কখনোই দূর করবো না।”

(তিরমিজি ২৬৫৪, ইবনে মাজাহ ৪১০৭)

অতএব সকলের উচিৎ সুখের মালিককে খুশি করা!

Lightspeed and Powerplay

Lightspeed, its low-latency wireless-transmission technology, and PowerPlay, a way to charge mice while using them on a custom mat. Both solve the main complaints some gamers have around wireless mice: that they’re laggy and could lose charge at any moment.

PowerPlay is the more intriguing of the two because it’s something we’ve never seen before in the mouse arena. High-end wireless mice might give you a charging cradle, while others usually pack a cable in the box to juice back up.
